It's just as simple as putting a piece of dry ice in the tank. Make sure the opening of the tank is the high part, once you see the little smoke coming out of the tankweld your heart out

I know it’s in Holley’s interest to advertise their stuff and all; but seriously huge props to them to sponsor so so so many of my favorite small-business youtube creators. It’s like together, two American-grown companies working together to keep our American gearhead community thriving. This is just too cool!

My grandpa used to weld on gas tanks by running his exhaust from his gas powered Lincoln into the tank and purging all the oxygen out of it.. This was in the 70s ,CO2,argon helium was very expensive and sketchy to find while carbon monoxide is plentiful.. This was in the oil fields and in his Texas shop.. I am not saying that Anyone should do it. However I have seen it done..

[@P-J-W-777]

Should have talked the customer into a fuel tank relocation kit. We moved the tanks on the 76 and 79 Fords which gained us room behind the seat and made the interior smell better and ultimately safer. We were also able to carry more fuel as well.

[@cbradley4466]

Dude, that fitting is going to break off!!!

[@yotarocket]

Yep, that fitting is definitely a goner 😂

[@fauxque5057]

It would have really been funny if they slid the seat back and snapped off the fitting.

[@christopherwedemeyer2993]

Dey gon' die.

[@coachster]

So Willie isn’t just a pretty face with a camera? Nope Great job guys. Lots of detailed instructions.

[@marlobreding7402]

Top Tip, 50 years experience. Use Gasgacinch cement to glue the cork gaskets to the VC and finger paint a very thin layer of RTV I perfer Black Ultra Permatex letting it dry. This allows you to easily reuse your VC gaskets without sticking while keeping the oil where it belongs. Also the gaskets peal off like sticky notes with brake cleaner to clean up the Gasgacinch. My engines don't leak. 23:50

[@karrpilot7092]

No, use the perimeter steel gaskets with the rubber liners on both sides. Chuck those cork gaskets into the scrap.

[@marlobreding7402]

@karrpilot7092 old school vehicles don't generally get o-ring gaskets. My methods are tried and true. BTW dad was one of the technicians that sealed Mercury, Gemini and Apollo space capsules. With hi temp red RTV the Original. First vehicle we used Red RTV on was my aunts 62 Buick 225 401 nail head. I don't have leaks on any engine i have rebuilt. Since 1966.

[@gwgrumblegoof3694]

Hey brothers all that is needed to weld a fume filled tank is exhaust gas from a running engine piped into the tank to drown out any flammable gases

[@XRod3308]

You can also fill the tank with argon or 75/25 mix. Letting the gas push all the gasoline fumes out.

[@tcloud69]

just run a compression test to what the PSI is at. if your around 130 psi your prob a 8.5-1 motor, if your around 170 psi your prob a 10.5-1. I may be off of my math but it has been over 20 some odd years for me. good luck guys.

[@thomascentanni365]

plug it into a laptop and smooth the timing table out. if u don’t the stock setting goes from idle timing to 36 degrees without a smooth transition.

[@garymessina1609]

Awesome refit awesome job great video thanks Steven and Willy

[@realoscaryarrito]

"Find Somthin' Kool And FIX IT" Holden Bros 2023. You should put that on a T-Shirt and/or Sticker. If only knew somebody that could do that.

I love watching you guys. You all make excellent content. Thank you!

[@connieholdenchambers548]

Sounds amazing! Everything is pretty and nice and neat!! Excellent work!!❤

[@markroper9269]

Cool video! Awesome looking truck!!!

[@kene6838]

Run your exhaust into the tank with the vehicle running for fifteen minutes, she’s good to go after that.

[@gregpeacock1794]

Thanks a ton for doing this video !!! i have a 72 F250 4x4 that i want to do this to but i will probably do the 2 bbl like you did on the 1210

[@williammitchell9566]

Picked up the same kit for my 64 Galaxie, also with 390, so I'll be referencing this video multiple times. Great video!

[@sethdunlap9868]

A funny side note too, for all the tree huggers out there, that might now be the most fuel-efficient big block on the road today. ...the factory probably stuck a big two barrel on it originally, making it STARVE and cause the driver to have to mash the pedal in order to get it to budge.

[@dan725]

Haha you’re right! This bolt-on system makes any old engine soooo much more efficient! And I think preserving old cars, yet with touch of a bit of modern, is a great balance to not blindly consume and buy the next new hotness. Preserving in itself is a form of being “Green.” As a city dude, the greenest folks I’ve ever met are those out in the country and hunters. Hunters preserve the land and leave it better than they entered it. The mantra I found that opened my eyes were those guys do want to preserve our beautiful lands, and they know how to do it. Not us city folks who consume consume and buy things in mass from amazon and the markets.. It’s so ironic the BEST naturalists, conservationists, and the greenest folks I’ve met are those hunting and rural communities!

[@kred3208]

Great job guys. If I lived in Tx I'd have you boys do all my chit. Good stuff

[@Savannahjbo]

WHATCHADO is .. get your biggest HOLE saw.. right through that floor, and mounts for the trans , hell even through the driveshaft ,what ever is in the way.. ziptie it down goodENtight, just keep that fitting on the bottom so your hammer, I mean pack of budlight dont slam into it when ya drag racing Matt in the Baja 9000

[@ptwccrider]

Clean install, definitely!! The Manifold Vacuum/KPA ,, seemed realy low not a very big camned 390. Great job on the install . Right on. By the way,, with the in cab tank, factory pickup, and a hard left turn.... It will definitely starve the EFI /factory fuel pickup,, with under half tank . Yes i own a 77f250 with a sniper and factory in cab tank. Luckily, i have a custom saddle and Rear tank with in tank fuel pumps and most importantly Holley Hydramates in both of those. All 3 tanks together equal 70 gallons of FUN!!! Very easy to plumb with ( 2 ), 6 port fuel tank switching valves. Ran by the Holley EFI Contact EFI PROS for the dual / 3 tank kit. Hooks right up to the Blue Wire on the Holley EFI.... FYI For Truck owners!! Enjoy!!

[@tomumn4216]

Awesome detail love it❤️

[@nenercat-br6hw]

35:40 you got it backwards. The truck is in open loop. It’s about to go into closed loop once it warms up it closes the loop using the oxygen sensor for feedback.

[@steveskinner9857]

Good job guys awesome job

[@Joatle]

Nice! Cheers from Norway :)

[@diyjeff1838]

I have that exact truck in f100 4x4. I love it!!

[@hemidart7]

Now that's a real truck!

[@ramonmacias9013]

I need to do this to my 1964 Ford Thunderbird with original 390 and carburetor.

[@davidblalock9945]

If you don't know what the compression ratio of your engine is, simple do a compression test on all 8 cylinders, and divide that by 14.7. So if your Compression test comes up with 140 ish psi, you have a 9.5:1 compression ratio.

[@pkpundit]

Fill the gas tank up with water to displace the gas, then drain it before welding.

[@r1g2v3]

Yup this works 👌

[@mikefarrell2333]

Great video! You have convinced me to run with this project on my 74 Chevy K10. I like how you used all AN fittings; I haven't had much luck with making the hose connectors with them. But, I like the clean look on the install of this truck. The truck sounded great too, did you ever get the follow up with the customer?

[@R0BY0NEKAN0BY]

Nice! 😎👍

[@danielduncan6806]

Some fitting, somewhere on Earth, is getting broken by getting hit with a sledgehammer, right now. So, somewhere on Earth a sledgehammer is getting its wings.

[@tomumn4216]

Awsome detail glad to see you guys are upping the class hope to see the cuba agin 🎉 I saw the video from Matt’s range day and you should not be afride of guns they part of our Texas history I know you guys are texans😮

[@vornice7604]

if anyone is thinking about this i highly recommend using Fitechs Force fuel systems for supplying fuel to your holley efi, way easier and more bang for your buck, thats what i did with my terminator x install, beats the heck out of spending hundreds more on a regulator and bunch of expensive lines and fittings that youll order wrong and then have to reorder.

[@robertandmaxwell]

Killer video! Just watched it again and wanted to see if there have been any issues in the past few months now that you have time on it? I tried a Terminator X system on my Chevy this past year but ended up back with a carb after many bugs and issues. It seems like Holley has invested a bunch of time into fixing things with this new release and I’m tempted to dive back in to the EFI world.

[@dangrass9783]

Literally just bought a 72 Highboy today with a 390. Buying the sniper for sure

[@toupocallen7572]

You're gunna break that fitting bruh

[@dalegereaux1863]

Dang it, now you make me wish I hadn't gotten rid of my F250 10 years ago.

[@TheEggeee2]

Mine had like a 348 or something. It ran good and strong when it decided to run.

[@ScottKirk-Notredcrew]

😍

[@brianwhite3258]

When are you guys going to collaborate with the Diesel Brothers???!!!

[@donnamoss9650]

Most of those trucks came with a factory coolant temp GAUGE -- NOT an idiot light -- which you apparently left NOT connected when you relaced the sending unit with the Holley temp sensor..... You don't care if the engine overheats and seizes up.

[@ericdolan2130]

Your best bet with the fuel tank is to have it steam cleaned at a radiator shop or somewhere similar. There is an OSHA video on a Surfboard shop that used a 55 gallon drum of Acetone to make a mobile work platform. Washed with soap and water rinsed several times, and left to dry for a day or so. When they were welding on it, the wire from the Mig gun punched through, and there was an explosion. Blew him 40 feet across the shop and Killed him. It was determined that less than a tablespoon of product had remained in the crevices of the drum, and that that is what caused the explosion. I've been doing tank work for over 40 years, my Father over 60, and we have never had an incident. Tanks are steam cleaned and checked with a LEL meter before welding. Please, please, don't take a chance or the cheap way out. Do it right. Anything else is just guessing. Maybe it's ok, maybe it's not. I know there are going to be lots of comments "I've just done such and such, and I never had a problem". Until they do. Good video guys. Cheers.

[@best7466]

So I want to put a diesel motor in my 2004 Mustang. What should I do 👀 but I would like to keep it a daily driver, and what’s a good transmission to pair it with ?

[@stevetomblin9007]

Holley dont make an aluminum intake for the 390?? The factory cast iron is heavy af.

[@DesertRox]

I would have put both filters before the pump as the pumps are very sensitive to particulate.

[@davidnelson1872]

Do the wipers and gauges and lights still work?

[@mbmike29]

That's now how I'd do it... lol

[@G-USA]

Don’t call me… lmao

[@chrisbigbendgarage634]

When I ran my sniper they advised against a dual plane intake due to air fuel mixture issues did they fix that issue if not you could get better performance by adding a spacer on the intake

[@jakecooper9900]

a 1inch open carb spacer under the throttle body eliminates the fuel distribution issues common with split plenum dual plane intakes

[@chrisbigbendgarage634]

@jakecooper9900 yes this is exactly how I solved that issue

[@brianlester5147]

If you put exhaust in your tank you can weld it all day

[@mr.e7261]

I want to know the MPG before and after the EFI.

[@matteedstrom]

8 Bananas on 1 Carrot^^

[@russellapplegate5661]

Make sure you have good roadside insurance... you will need it. Just a matter of months for the brain quits on these. Carb will always get you home

[@Robrt32]

I wish I had all those parts on my 390. I’m poor,I can’t buy it and Holley won’t give me sticker much less that kit.

[@danielj2839]

How much would that cost

[@berhorst59]

Been wanting to convert my 71 highboy to EFI, but hesitate because it has dual tanks, and the return line and a switch valve that also has return capability are proving problematic.

[@chadrech9230]

My buddy did it to his 69, but eliminated the cab tank. Had it installed using just the Aux tank. Works flawlessly up and over Donner Pass from Sacramento over to Nevada where his folks live.

[@zacheryandersen]

What was he putting in the intake manifold port? I've been trying to figure out where to put the temp sensor for the Sniper 2. All my ports are currently being used. Can I just add a fitting like the one he's using and place two sensors in the same port? kzbin.info/www/bejne/jYbdh4iap9-LfpY

[@brandonb4462]

Hey... Love y'all's channel... Just one thing... Your music is way to loud! I find myself constantly turning the volume up and down throughout your videos... Don't mean to complain... Just something I think might help your production value. Lol

[@jamesw1791]

I think the cost of this the way you have it set up is around like $2,500, is that correct? I'm not sure if it's worth it

[@user-rw2tw8yl4l]

are these guys JUST bros or twins?

[@apocolypse11]

$5000 in parts lol. If i want modern efi ill just drive my 3.5 Eco boost an drive my old carb,mechanical fuel pump, distributor dodge lancer on Sundays.

[@roberts208]

fill the tank with water before you weld it

[@keyboardheroism]

Flood the fuel tank with c02 or N. Inert

[@adrianmoffat9741]

could you please be more steady with the camera. or maybe buy a gimble so its nice and smooth. just saying

[@65cj55]

Put the Factory Valve Covers back on and find a original Factory Air Cleaner..

[@cliffordlatko1901]

Spngebobs says.....and thats the parts...2hrs......later

[@cliffordlatko1901]

Dude, gotta flash it first with some water in it.

[@bondfan778]

Great video but that whine in the background is really annoying. It makes the video hard to watch.

[@dennyauman5449]

Good luck with that junk. "Self tuning" ha! ha! What a lie...
