Bronco Holley Sniper EFI Self-Tuning Kit Shiny Finish Installation 

You really should talk about the other prep work that needs to be performed before attempting to install a Sniper EFI setup. You have to make sure your engine (vacuum leaks), charging (sufficient volts generated), exhaust (no leaks, and welded on O2 sensor bung), and ignition systems (resistor plugs, high quality plug wires), are all sorted out before starting a Sniper install. This is a critical prelude.

Super video on the Holley Sniper EFI, Installation. It was very educational & clean job. Now I feel the confidence to install my own !! Greetings from the United Kingdom & East Africa. Many thanks !!😊

Just a quick tip that worked for me on drilling a gas tank. Put a magnet from an ATF pan behind your hole while you drill it, catches all the metal shavings.

That Bronco is sweet. We rescued a 72 and are getting it back on the road at Fire It Up Garage. Thanks for the video.

This guy knows just enough to get in trouble.

Great video. Nice start to finish tutorial on the install and I really appreciate the section on how to make/install the fuel return line. I was thinking of purchasing the FI Tech 3003 system but after watching this video, I am going with the Holley.

Great informational video

The return line could go into the filler tube or hose. Not below fuel level ideally. Any rinsing of fuel tanks must be done with boiling water.

Great service thanks

One thing about the design having the ECU built into the unit is that the heatsoak the aluminum body will exhibit will cause the ECU to break down from thermal breakdown as their other ECU's like the Dominator and TerminatorX cant be near an engines heatsource like headders etc so the design should go through a design change placing the ECU in a remote location...I also think making the throttle body out of composite plastic would of been a better way to go as composite pastic doesnt act like a heatsink like dense billet aluminum does

Is the background music necessary? A distraction

Great video! Learned a lot!

A .Super video on the Holley Sniper EFI,its was very educational,clean job.now i feel the confidence to recommendation instal my Dodge Ram charger 1978 v_ 318 cumi boite auto (what type of kit HOLLEY SHINY SNIPER EFi for my dodge instead of the carburetor great have nice day

Alternatively, you can drop a couple chunks of dry ice in the tank and let sit for 20 minutes. Fills tank with CO2 and prevents fire hazard.

when the tank fuel level is low that fuel return is gonna make some foamy fuel! mmm like a latte

I'm interested in the fuel tank itself. Is it a stock bronco tank. I have a 73 f100 with Jaguar XJS irs suspension . I need to get a rear mounted tank like this one. Will it fit my truck. Mine was in the next frame space forward. Which it taken up by my irs rear suspension. Where can I buy that tank? CJPony parts?

I see you took out the temperature sending unit, where did it go? or does the harness for the sniper have a gauge output? Thanks.

I really enjoyed how you broke that down im intimidated with fuel injection the electronics but I have a 1971 C10 Chevy pickup with a 1971 Cadillac 500 engine 1995 Chevy Dually bed but the duelly flares are filled with some 31inch or so tubbed out tires this truck looks like a 10 second truck but its a total highway cruiser a highway monster but my point is this truck was a total resto 18 years ago and we've owned it for over 15 years but it needs to be updated its a great truck vintage air the caddy taillights no bumper rollpans and billit grills really great done trk but im lost with whats in that motor i didn't build it i no caddy high performance parts were never cheap and easy to get especially 20 years ago but it has a aluminum intake headers sounds like it has a cam im sure with all the other stuff MSD but i figured if i went with the throttle body it would adjust whatever combos in the motor to run its best 1 question is that holly unit just say my motor needed a 850 cfm wich i hope not would that unit provide it another thing I no how important with today's fuelinjection is your O2 sensors so wouldn't 2 O2s be better or is this not the unit for my situation either way you really opened my eyes up to its not a nothing job buts its not what i thought i really want to start putting LS engines in all these old cars my father and i have has theyd be perfect but like the throttle body i dont like wiring i wish u made a video like that one for GM LS installs anyway sorry for the long comment i wanted u to no what im dealing with and comment on how good of a job u did to break it down thanks again

I would be quite ashamed of how the pre-filter and new fuel pump were mounted. A fault liability if ever I saw it. There was a huge bracket to play with to plan a much neater and safer installation. If this were to be used off-road then there is a major chance of the pump/prefilter combination being ripped off when snagged by a tree branch or such like... and lets not go into the planning of cable runs, no shortening or neatening up, no tidy up of throttle positioning sensor cable, nothing nicely tucked out of the way using p-clamps or the like. A bit of a bish bash bosh job. Glad I think about these things a bit more when building PC's! Greetings from Scotland by the way!

Where did you tap into for the ignition source

I recently purchased a car and it already had a holly EFI kit on it. I think they have it wired to the solenoid. Is that ok or should I re run it to the battery?

Great video but buy some Unibit Step Drills, they make a better hole in thin stock. That EFI is what I plan to use in my last hot car.

what happen to the post fuel filter?

if you have a regular HEI distributor where would the yellow wire go that you hook to the negative side of the coil and do you have to set other settings like icu numbers, maf numbers etc? THANKS

Do you know the part number for the fuel return kit

Will these EFI work on a 1996 Chevy pickup with a 6 cylinder engine ?

The best video , thank you

If someone was changing over from shitty 80s efi in an 88 model f series to this, would you have to run a fuel return or could you use the stock one? I’ve put enough time and money into troubleshooting that garbage and I’m looking to try something else and this is a potential solution I came across.

Hi brother. Just a question. Does EFIs just fit exactly (bolt holes, opening diameter, etc) where the carburetor is removed from ANY engine? In other words, are carburetors sizes and mounting standard like house hold mains sockets? I do ask because I have watched a number of videos on how to swap carbs to efi and I have find none that warns on the mounting fittings or adopters or anything of that kind. I want to change my 1991 suzuki vitara carb to efi. hence I have been trying to learn how to. Thanks in advance

should have cleaned that body connection for the ground next to fuel pump for better connections.

Where did you come up with your 12-volt ignition source on the bronco?

I think it'd make more sense to install a T before the fuel pump for the return. It would be easier, all the fuel would do is re-circulate through the pump and back again.

do i need to run a inline fuse with that fuel pump relay or is there one already built in ?

Any idea on the idea of how much airflow I will need for a 460/429 with cobra style heads? And mabye which efi kit you would suggest.

Thinking I'm going with this on my 79 Chevy but it's s step side wonder if I should do away with the tanks and put a bigger tank in the middle of the frame on the back of truck.

This dude cracks me up. Lol

does the switched 12 volt have to be to its own source? cause i just bought mine and i have no ignition wires by themselves, so is it ok to splice into another switched 12v?

who makes those push together fuel line fittings, part # ?

Very helpful. Thanks

Is that a factory gas tank for the bronco? I'm planning on putting a rear gas tank on my s10 where the spare tire goes and I like the design of that tank.

What if you have an MSD HEI distributor with the coil built in?

Would you do a kit for a Kawasaki motorcycle twin carbs 500cc 1994. In case you do not deal with it do you know anywhere that I can find it. Thanks

great video. who is that playing in the background music. i think i know them,but would like to know for certain. Once again,Great video.

Any reason why you can't run the return line into the filler neck?

I have a 90 F-250 with a 460 that I would like to put this kit on, but for the return lines, how would that work with dual tanks? It has the old EEC-IV FI right now.

Love those valve covers where did they come from

To Swap the Bronco OEM Carburetor you need: Holley Sniper 550-511K - Holley Sniper EFI Self-Tuning Fuel Injection Systems; New air cleaner Fragola Performance Systems 483106-BL - Fragola Performance Systems Fuel Cell Bulkheads Are this the only parts you need?

I just installed my sniper EFI on my 69 mustang and the hand held LCD is saying it cannot connect to the ECU and I can't find anything on this matter online

What carb replace is Best ? Holly sniper, FiTech will run timing will Holly ??

Is there a problem with putting the return line below the fuel level in the tank?

Hello im Julian i own a coupe mustang 5.0 Holley 600cfm all stock , but i live in Calif my conccerd is it smog legal?. Serveral years ago i was running problem that i keep replacing 3 times on Holleys for new one's then went over to have them rebuilt since they don't make these 6oocfm anymore. I was looking toward dumping out the whole engine to complete EFI engine. But that a whole lot of money,This might help me alot Holley Sniper,oh i'am running a small MSD Coil, but no modul brain box

Yeah the wiring is probably simple but what about the settings on the hand held controller

any concern of the drill shavings left in exhaust when drilling for the o2 sensor?

No problem using a dual plane intake?

A number of things done that were questionable to say the least. #1 is the fuel pump should have been wired into the pump driver wire from the FI unit, this is a safety concern, as fault or failure of the fuel injection system would kill the pump so high pressure fuel isn't sprayed out. #2 is the improper cleaning of the tank of metal shavings, relying on the inline filter to catch injector damaging particles is not a good idea, especially since the tank was down and could have been easily cleaned.#3 is that the start up procedure in the installation directions wasn't completely followed, at least you didn't show all the steps. The final step before starting is to perform a test to make sure all sensors were operating properly, which you didn't say to do or show that you did it. A few other smaller issues also, but those three were most important. And, FYI, the reason for fuel injection hose clamps is that they are smooth so they don't damage the outer hose cover, not for any superior clamping force. The other big thing that I forgot to mention was that you put teflon tape on the fittings in the fuel pump, and they are supposed to be installed DRY and they should have a gasket to seal them!

I have one of these ordered from you guys,would of been nice if you had expained in this video where you get the 12v source as there appears to be nowhere on my 75 ford that provides a good 12v source during run and crank on the key resulting in an extra switch to turn it on before i can use the key to start :( That information in this video would be far more useful than the unnecessary music in the background distracting everybody.

good video, just the music, the looping was driving me nuts! at one point, I had to mute the video and switch on the CC....

It was so funny when he dropped the coil nut and the nut in the tank I died!!! Also the fuel pump supply wire was there for a reason that's what the relay is for geez it's not rocket science I know it's hard for a man to do but read instructions

dont you need a psi regulator?

just did mine today 5/28/17 There is A TICK TICK TICK Like A BBQ or Stove Ignitor what is that? is it normal? its magnified inside the cab of my tuck even though its Dyna matted and Carpeted does it get less as I adjust the unit? I only left it on a few minutes have not gotten to 160 yet temp wise I'm checking for leaks or other Associated or even non associated wires I might have pulled off or tweaked while changing over to the Sniper on my C10 Chevy 350 V8 I hope that Tick sound goes away or I plan on getting rid of it otherwise I will go nuts 1000 bucks PLUS down the Drain if this turns out to be junk God I hope not.

Will this work for a 1977 Ford ranger truck 360 or 390 ????

Will this work with force induction?

My car with carb and electric fuel pump.. Has an oil pressure sensor.. If I loose oil pressure it shuts the electric fuel pump off... Oh and it seemed rather stupid to me to cut the wires off on the old fuel pump so short you can't use it on another project ..

I love that music! What's that group's name? It's awesome!

this is a 302 engine?

Why did you cut the wires so short on the old pump.... Keep Wrenching Brotha!!

Can you install this efi with factory wiring harness?

Will the fuel return line work T into the small rubber over flow line next to the filler hose? it is on top of tank and No Metal drilling .

Nothing about fuel tank venting?

Did anyone else cringe when he cut the fuel pump wires so close to the old, perfectly good pump?

Whats difference to the Terminator EFI?

Where did you guys get that air cleaner?

Will this kit work with a 351 with aluminum heads and big car HCI basically

Does the fuel pump run 100% of the time? Or does it shut off when the regulator shows full pressure?

Can we use for blow throu turbo ???

"Connect the EFI to a 12 volt power source, it can't be connected to anything else." Where the fudge do I just "find" a 12v power source? That could have been explained a little bit better.

Did he say he wants to do a reach around?

The dual-plane manifolds don't play well with EFI.

Wish he would have dynoed the engine first with a 4 bbl carb, for comparison............. :(

haha "fuel injection hoseclamps" lolololol

Kinda funny. You guys used the obviously wrong type of throttle cable bracket

The hose you used is 50psi max,, 60psi fuel pressure. And yes efi hose is different and beware of cheap chinese hose. Or any cheap hose! That externally braided hose used to the throttle body is almost certainly going to fail! As does all the pretty bullshit externally braided hose. EFI pumps should have a relay as well, ideally even 6lb Holley pumps as well. It saves them from failing. The return line really should be a steel pipe, rubber hose should only be used as a joiner and with ethanol blend fuels has about a 2 year life,,,, ask how I know!!

sry chief, u got nothing on bill, lol.

I bet that system costs north of 1k

Why is this man using a drill bit made for wood?

WTF!!! CRAFTSMAN TOOLS!!! DONT YA KNOW YOURE NOT PROFESSIONAL IF YOU DON’T HAVE SNAP-ON. JK BTW. I LOVE HARBOR FREIGHT.

lose the music and your brake booster should not be T'd in to constant vacuum leak/ pcv valve.

Come put mine in..lol

You dont get the full potential of the sniper, mounted on a dualport intake. Best solution is a single intake.

Why not start with the price? $1000 + work :))

Gas tanks can be dangerous. There was some gas and lots of fumes in this tank. Drilling metal can cause sparks. The two don't mix well. There are appropriate ways to work on fuel tanks and this is not one of them.

1000 DOLLAR NO WAY

Music sucks. Screw drive to loosen the nut on the sending unit? Not safe

Tell them to drain the fuel BEFORE you start drilling....

Take out the music... smh

Always being shown on a single fuel tank set up, never once has anyone bothered to show a install on trucks with duel fuel tanks. Seriously though if you love that Bronco take care of that rust.

I've never seen some one waste so much time dropping at tank and putting a return in.

Wow just waste a fuel pump by cutting wire to short to use anymore, money no problem I guess for you guys

Sadly from 2030 on all combustion cars including classics will be banned from public streets in entire EU and Scandinavia :-( In Germany the Green Peoples Party gave order to shorten fuel supply from 2025 on by reducing all conventional fuel stations to only one state operated central gas station per city or county. Now they even want to slow down all the gas pumps from 20 litre per minute to 2 litre per minute...From 2027 on in the EU certain car spare parts will be banned too....as exhaust systems, turbo chargers and even some engine and gearbox oils...California and New York will do the same from 2027 on.... So no investments should be done in oil burning cars any longer....They even created a new kind of crime here, called emissions and smoke crime. Called "Bundesabgasbespaßungsverbotsverordnung" in German.... :-/((

Music is horrible.
