How do you open the gas cap with 60 psi and not have it knock you over. I'm missing something.

It doesn't pressurize the tank, it is the pressure into the fuel line to the engine. The tank has to be vented anyways.

Soo, if you send it out at that pressure, the tank vent has to let air in at that same rate, I think. If not vented the pressure could not be kept up, so not being vented enough could cause problems of low pressure. ???

Vented gascaps are usually always a good idea... esp if you live in a high temperature change area.

Aka I fill my tank now (45*F) and in 2 weeks it will be 70*F and sunny one day.

doesnt take long.

When I did my suburban tank I used the factory Camaro pump and housing, I just cut it off the Camaro tank and welded it onto the suburban tank. That maybe an option, suburban tank with newer Silverado flange and pump., I left my stock suburban fuel sender in for the gauge.

Return pressure is typically much less than supply pressure. Volume and pressure is lost because of the fuel used by the engine.

Any pics of this tank? Or part number?

The older, non EFI senders are a smaller diameter.

Let us know what you find.

Correctomundo........ I had star Dyno in spring branch Texas install a Silverado fuel pump and sending unit in the jeep tank I used. I paid $75 for the tank new and they baffled the tank and installed the fuel pump and sender for $450.
I think Terry said that he had to shorten the depth of the pump.

I tried this on a chevelle I did since the caprice tank is a nice replacement in the 70 chevelle. Even the impala SS fuel pump won't produce enough pressure.

lots of good info here has anyone considered using a pump from the 96 full size truck with the 350 vortec. its pressure specs are inline with the ls engines not sure of volume tho. 96 is the only year that had the replaceable pump that will fit in the s10 hanger. in 97 they went with the module assembly.

That dog won't hunt.... Tried it......

I was reading through this thread this evening and am thinking about a 19 gallon blazer tank and module ( they are cheap on ebay) for my 61 project.

I did an 98 s10 ls swap last year and the stock pump worked fine for the 5.3

I have an original cluster with the gauges I'd like to use in the truck, but if its not practical I'll upgrade to modern gauges.

I'm curious as to what you all are doing for a fuel gauge, any one using the stock gauge?

If so how is it done?
Thanks, Bud

The 1994 S10 and many other fuel tanks, as Blue666 points out, have intank pumps with sending units that can accept LS pumps (58psi). There are many sources on eBay for these. The filter and pressure regulator I will use is the Wix 33737, used on the '98-'04 Corvette. To make the lines simple, I will use braided stainless steel from Earl's Plumbing with the hose ends that plug into the factory fittings. We must be cautious to use the new hose that will stand up to today's crappy fuel. Remember that these are nothing more than glorified rubber hoses, so check with Earl's to ensure that the hose will last.
I will post pix of the install when I can get out there to work; it is still cold in GA
I forgot to mention that the pump that Potak and Bryant recommend is the Walbro 340, which is readily available on eBay. I haven't ordered mine yet, but the pix indicate that it will be a drop-in deal for the S10 tank.
With the S10 tank, Walbro 340 pump, Wix 33737 FPR/filter, and Earl's lines, this is the most simple and lowbuck setup I can imagine.

2004+ LS setups use a pump that has the regulator and filter built into it. Have you considered using one of those? Do you have pics of how the S10 tank fit, specifically how far below the frame rails does it sit?

How did you mount this, and do you have pics of what it looks like from below and behind?

Lower frame rails were trimmed approx 1/4-1/2 " to allow proper fit.

Looks nice. Is the filler neck going to clear the frame rail?

Tucks up nice and high, hard to see from behind. I can't take credit for this install, other members pioneered this before me.

Any pictures of how you made your tail light hinge? looks awesome, good work!

This is during mock up on a spare bed corner, a great friend made this for me. I certainly couldn't have done it, LOL.

Whoa how did you get a filler with no cap?

Re: LS engine swap into 1966 c10; fuel tank install
 
Ford Escape filler=no cap.
