Bronco Holley Sniper EFI Self-Tuning Kit Shiny Finish Installation

hey Freddie with CJ Pony parts it's been 26 years since the last car boarded cars were produced in the United States and while we've given our 1968 Bronco a lot of modern amenities it still has a carburetor when we originally built it we did plan on going with fuel injection but because the time constraints we ended up throwing a carburetor on it and today we're going to improve the performance and efficiency of it by installing this Holley sniper EFI self tuning kit this Holley sniper EFI self tuning kit is going to replace the outdated carburetor on our Bronco it features an internal ECU map sensor and a fuel pressure regulator for an easier install and it can even self tune with this EFI kit we won't ever have to worry about altitude changing out the Jets code starts chokes and it's going to make the overall auto and performance significantly better this kit is a direct fit replacement for your carburetor and includes everything you need for it to work but it does require a returned fuel system which can be purchased separately tools you'll need for this installation a good set of sockets and wrenches tools for drilling and also wiring the very first thing we're going to be doing to the Bronco for this EFI kit is draining the gas tank since we have to do a return line to the fuel tank we have to drop it and drill into it so we're going to drain the gas tank first to drain the tank all we're going to do is take off the fuel line from the tank that goes to the fuel pump and so we don't make a mess we're going to clamp the hose shut if you notice our Bronco already has an aftermarket electric fuel pump on it but we will be replacing it for this Holley kit and unclamp the hoods then you can just let it drain into the tank now when you're doing this feed mindful of how much fuel is in your gas tank we're thinking ours might have over 10 gallons in it see might need a fair amount of extra gas tanks to hold on the fuel the tanks empty now we got the boring part out of the way we're going to put the hose back on the pump and then move up to the front of the truck put the fuel tank empty we can begin the process of removing the carburetor before we get any work done we're going to disconnect the negative battery terminal on the battery just to be safe disconnect the throttle cable this Bronco actually has a throttle position sensor we have to disconnect to you we just need to push these tabs right here to release it from the brackets disconnect all your vacuum lines Oh disconnect the fuel line and pull off these connectors now we can actually remove the carburetor from the intake manifold remove all four nuts to remove the carburetor put the carburetor off make sure the mating surface is nice and clean and install the new gasket install the new fuel injection unit with the logo facing the front of the vehicle and reinstall the four washers and nuts to hold it in place before we install the throttle cables on the EFI unit we have to transfer over these pivot joints you and so the pivots onto the Holley EFI we're now going to reinstall the throttle position cable reinstall the throttle cable it's time to install the core temperature sensor for the Holley EFI unit but we ran into a little issue that most you probably won't run into we have an aftermarket coolant temperature gauge right here and this is the only port available on the intake manifold so we're going to remove this sensor and saw the holley sensor and then relocate this put some thread sealant or thread tape onto the sensors and installed in the intake manifold grab the purple connector and plug it into the sensor we're now going to install the fuel hose onto the fuel injection unit with this a.n fitting and I'm going to show you how to put this together you're going to take the fitting apart and slide this sleeve over the hose then you're going to lube up the barb right here with some wd-40 or some kind of lubricant and you're going to push it on now this is fuel injection hose so the hose is very tight and it's going to take a lot of force to push this on we're just going to push it together and you'll end up with this result connect the hose to the inlet of the fuel injection unit all right so the EFI system knows what's going on it included an oxygen sensor that we have to install grab the connector that's on the efi unit and plug in the oxygen sensor then you need to find a location to mount it you want it after the header collectors so you're gauging all the cylinders on that side ideally it would be for all eight cylinders but this is a dual exhaust and we don't have enough wire to put this after all eight cylinders collect so we're just going to do it on bank one and you want to install it in an orientation to where it's ten degrees or more above being horizontal in order for moisture to drain off of it so that sensor doesn't get damaged we pick the location on our pipe right here and it comes with an o2 sensor bung that we're going to clamp on to here put we need to drill a hole in this pipe first we mark our hole now we need to drill it up at 3/4 of an inch with the hole drilled you're going to install the provided gasket and then the oxygen sensor flange and then you're going to put the supplied hose clamps around it to secure it in place you could also weld a bug on here if you want but this is included in the kit don't tighten the clamps down just yet in case it gets misaligned then grab the oxygen sensor and you actually don't need to put any anti-seize on there it comes with it then thread it on to the flange there we go alright then tighten down the clamps tighten down the oxygen sensor we can now begin working with the main harness we're going to start off by running the main connector off the EFI unit down here on our the spark plug wires and grab the main connector plug it in and we're going to mount this relay right here on the wheel well and then we're going to connect the ground and power wires to the battery right here and then we're going to have plenty of room to connect this yellow wire to the ignition coil we're going to use a self-tapping screw to mount the relay just like that this yellow wire connects to the negative terminal on the coil right here but I think we have a little bit too much wire so we're going to trim it down and then terminate it strip it crimp it then use a lighter to activate the heat shrink take the nut off the negative post on the coil and put the connector on the coil it's important to note that if you have an MSD box ignition you do not want to put this wire on the negative part of the coil only do this if you do not have an MSD ignition box now we're working on this pink wire this is the main switch wire for the whole lit system it needs to be connected to a 12-volt ignition source and we have a 12-volt ignition source right here it needs to be its own clean source that can't be connected to anything else so we're just going to connect the pink wire to here and I move on to the next one the pink wires just a little bit too long so we're going to cut it to an appropriate length and connected to the ignition source at this point if you want to you can permanently install this unit right here simply grab the connector that's on the EFI unit and plug it in and then if you want to permanently install this you can run the wiring through the firewall and then mount this somewhere on the dash or in the interior somewhere however you don't need this hooked up at all time so we're not going to do that we're going to go for a nice cleaner look on the inside so we're just going to hook this up for monitoring when we first do the install but we're not going to leave this permanently installed so we're not going to run the wiring but if you do just simply find a grommet in the firewall and if you don't have a grommet just drill a hole and put a grommet in and run the wire this red wire on the main harness has to go directly to the positive terminal on the battery and this black wire has to do it directly to the negative term on the battery we're going to use the supply connectors to directly connect them to the battery we're still going to leave this disconnected for now but we're finished with this part we're finished with the wiring for this Bronco now but you're probably wondering what all this extra wiring is this is an optional harness that we will not be using for our truck but this is for if you want to use it for electric fans or your AC fans but since we already have a switch for that we don't need it this blue wire is actually for the fuel pump if you don't already have an electric fuel pump set up this has a built-in relay for it and this is the power the fuel pump so we won't be needing this as well and then this wire is for if you have like an MSD box type ignition system and we don't have that so we will not be using this connector either with all the wiring complete we're now going to reconnect the vacuum lines but we needed to do some modification to our current setup we needed to get a longer vacuum line for the distributor because all the fittings are relocated to the rear of this unit our fittings were in the front so we needed a longer vacuum line for the distributor and now our PCV and booster line you need to go to the EFI unit but there's only one big port so we needed to get a tee fitting to put these two hoses to it both of them are a little bit too long so we're going to trim them down to make them fit nice install the t-fitting then take one of the sections that we cut off then use that to connect it to the EFI unit just like that now we can connect the distributor vacuum line all the wiring up front is complete and now we can start working on the fuel system this Bronco does need a returned fuel line for this to work so the first thing we're going to do is disconnect all the hoses again and drop the tank we did drain this earlier but we're going to be cautious just in case there's any more fuel left in there there's a little bit left we also have to disconnect the filler hoses and disconnect this connector to the sending unit to minimize the mess when I lower this gas tank I'm going to take a bolt and put it in the hose that goes to the fuel pump just so no more fuel can come out with everything disconnected from the tank you can lower the strap you we're going to be putting the return line right here on the tank now there's no access panel or anything for this tank the only thing that there is is the sending unit right here so we need to put a nut on the inside of the tank and you don't want it to be too far away from here because you have to get inside the tank to hold the nut so you want to close the sending minute for an access panel if you have one now we're going to remove it be careful not to damage the sending unit with the tank out of the Bronco we can now work on installing the return line in order to do that we need to drill a hole in the tank right here to install a bulkhead fitting now this bulkhead fitting did not come with the Holley kit and you will need to get this if you want to do the return line properly the bulkhead fitting we're using from Russell is part number six seven zero eight five zero and you will need this to properly do a return line in your fuel tank before you start drilling a hole you want to make sure where you can install the return line we had a lot of clearance issues with this tank the frame basically ran right here so we couldn't do anything above this line because there was a frame here and it's set pretty much flush with the bottom of the Bronco right here so we couldn't do anything up top you want to do the return line as high as possible but like I said we can't really go above this line because the frame and this is the only opening in the tank so in order to install this bulkhead fitting there's a nut and a washer that you have to hold on the inside of the tank so if you were to do this too far away from the opening you wouldn't be able to hold it so you need to find out where you can reach around and get an approximate distance of where you would be able to hold this nut and in our case we're looking at right about here that's what we're going to drill the hole that's as high as we can go and also as far away from this hole as we can go I want to start off drilling the hole just like this but once I get it started I'm going to flip the tank up like that so the shavings don't fall inside of the tank and down here to where I can get them if I drill it like this on the edge of the table I can get my hand inside of the hole and just wipe out the filings we're going to start off drilling the hole with a pilot now that we got it started we can upgrade to our bigger drill bit it's important to note you want to get as much or all the fuel out as physically possible in our case we drained all the fuel out clean it with water and let it sit overnight and make sure it was completely dry before we did any drilling put the longer end of the fitting in the hole then install the washer and then the nut let's see if you were doing this away from this access hole right here there'd be no way you can do this to hold the nut on the inside of the tank you might need a flexible ratchet head like this I can get the ratchet head in there then you can get it on the nut and then tighten it with a wrench you need to make sure this is tight so it does seal but you also don't want to over crank it because these are aluminum reinstall the o-ring for the sending unit with the bulkhead and the fuel sender in the tank we can put it back in the truck reinstall the tank tighten the clamp on the filler hoses reinstall the fuel tank strap since this is a fuel injection system and the Holley kick came with a fuel injection fuel filter we're going to replace this fuel filter with a Holley filter now install the Holley fuel filter in the fuel injection line this filter only goes one way so make sure you have it orientated right this flat part with this I guess cap section is the outlet and that goes towards the fuel injection unit install the clamp on the other hood we're going to connect the return hose now I installed a barbed fitting just like we did on the feed side and just thread it in to the return side of the fuel injection unit now there are three feed ports on this unit there's one here one here and one here you can use whichever feed you want but there's only one return you have to use the return on the fuel pressure regulator which is right here with the return line connected to the EFI unit we can just route the hose back to the time since we're converting this to fuel injection this pump that's currently on the Bronco doesn't produce enough PSI for it to work properly so we're going to take it off and replace it with the Holley unit now there might be some fuel left in this house may take it off so be careful unbolt the pump from the bracket we're going to cut these wires right here at the fuel pump and lucky for us now we have wires already ran for a new Holley fuel pump but if you don't already have an electric fuel pump Randy will have to run wiring for the new fuel pump we're going to put the holley pump right where that fuel pump was put the brackets on it and we're going to melt it right there all right remove the plastic plugs from the fuel pump and install a barb fitting with thread sealant on each side Bergin saw the first fuel filter that's the good between the tank and the pump and this little Ridge right here has to go towards the engine and the flat side goes towards the tank and we are in a pretty tight quarters here so we're going to make a little loop to connect this filter to the pump it's not going to be a straight shot and on this hose you can use just regular hose clamps but after the pump on the pressure side you're going to need fuel injection hose clamps because the excess pressure with the fuel pump mounted we're going to connect the power and ground wire you it's important that you get these wires in the right position because if you switch them up the pump will go backwards because this is now a fuel injection system and it's going to see higher psi you need to swap out this regular fuel ters which went from the metal line to the pump you need to swap it up for fuel injection hose before we finish the fuel feed line we're going to do the return now that we have the bulkhead on the tank we can thread on this 90-degree fitting and we have a return hose ran now we're just going to see about how long we need to cut it and it's looking like we can cut it right about here we have the aen fitting on now we can put it on the tank you probably won't run into this issue but the flair that we had on this metal line right here was too big for the fuel injection headers so we cut it off and put a compression barb on here install the fuel injection hose make sure you use fuel injection hose clamps and we connect you to the fuel pump and tighten up the clamps it's also a good idea to replace any other regular fuel hose you have with the fuel injection hose so you don't have a week the very last thing we have to do while we're back here is reconnect the sending unit connector now you can reconnect the battery terminal fill the tank up with gas and then check for leaks all right so there's no leaks everything seems to be good now we're going to clean up the wiring we took off the air cleaner stub from our carburetor we're going to swap it over to the Holley unit they do provide you a stud in case you don't have one you now we need to configure the efi system for our bronco go to the wizard select our efi unit next this is an eight cylinder and set it to 302 target idle will make it 754 now we have a stock cam in here no power adders and we just have a coil we don't have a CD box or magnetic or a dual sink stock can snipe here and now it's going to configure it now we're going to check and see if our update saved and there we go it recognizes that it's a 302 v8 with a stock cam and now we're going to start it up the Holley snapper EFI system is installed the Bronco runs in idles great it started up super easy now that you have it running you can go do some more fine adjustments with this and do some data logging installation should take you about better part of a weekend and before you know it you'll be heading down the road
