I like how you recommend dow corning 730. Been using it for years. Gonna laugh my butt off when people Google search it and find out it's $100 for a 2.5 oz tube lol. Fantastic product though.

For used tanks I've used dry ice, it's frozen carbon dioxide. Put a couple of chunks in the tank before drilling the hole.

Will the new unit not fit into the stock location? Do you need to plug the lines to the original unit?

[@IDIoilburner]

Good question

[@trentdawg2832]

I stick my empty tank up to a running cars tail pipe to remove flammable vapors with inert gas (exhaust)

[@sergeantspeed5941]

That's actually pretty smart lol

[@dandorris8531]

Nice product, most cars can’t even accept that as they don’t have that much space above the tank and the trunk floor. Sticks up to high.

If anyone is using the 19-355 Sniper universal double pumper fuel module and you need a steel shim, a GM 200-4R forward clutch steel plate will work fine. The ID and the OD is perfect. 😁

Great video and great design for the pump.

[@limegreen192]

I just installed this pump. The bolts for the hold downs in my opinion will be a problem in the future They use a very small Allen head bolt into an aluminum lug. If this gets any corrosion it will be very difficult or impossible to remove the pump without cutting the bolts.

Does this fuel pump need any fuel pressure sensor? I am running a 6.2 L92 with terminator x in my 1952 Ford Sunliner. I am trying to lign out everything i need for fuel.

[@tokslut]

What did you found out? I am looking at this for my L94 but they don't list this for the Terminator system

[@SCSS2024]

@tokslut not sorted yet. I bought it though, so hopefully it works out.

[@tokslut]

@@SCSS2024 OK, thanks!

c02 fire extinguisher and fill the tank with the extinguisher nozzle.

[@cjs9477]

can you install this unit on a bit of an angle? i dont think i have enough room to put it right on top of the tank

[@kevinlund1628]

Does the hydromat eliminate the need for a baffled tank?

[@keithgarrett6512]

Mine is failing the pump regulator stopped working and gauge is now pegged out over 100 psi just 500 miles and past the 90 day warranty.

[@mendozaconsultation]

Question. I have a 93 Ford E150 5.8L Club Wagon Van 5.8l EFI. Can i hook up a in line/exTernal fuel pump to the wiring of the pump in the tank since is already hooked up to the fuse BOX,and how?

[@ScottDLR]

I need something like this for My Sniper setup that will fit an 18" tank. Is there anything that will work?

[@peterhatch1583]

I have a 1986 surberbon can I convert that tank to this

[@JohnSmith-qj4cf]

Do you have to buffet the tank for efi??

[@larryfogle3697]

Sucks if your tank is your trunk floor.

[@PeterHatch-mx7zc]

I cant afford one !

[@lancebaker7711]

The math on cutting the tubes is all wrong! You need to reduce the length of the tubes by the difference between your depth and 12 inches. For example: My tank depth is 10.5 inches. If I used the 12-10.5=1.5 inches of tubing as indicated in the instructions, I'd cut my tubes down to 1.5 inches and my pump would be suspended half way up my tank. I'd run out of gas at half a tank! What the instructions should say is: 12-10.5=1.5 inches of tubing to remove. The math in the instructions is totally wrong. I can only assume people with enough experience in working on cars figure that out.

Okay… I thought it was just me..!!! Thank you
