The Stovebolt Site Forums The Shop Area The HiPo Shop gas tank question

I've got a TBI 350 in my '46. I need a gas tank that'll fit between the framerails, but delivers the right fuel pressure for the fuel injection. Will any tank with an internal pump from a fuelie vehicle work, or do different fuel injection systems use different pressures? I looked at an external pump, but for one that delivers enough pressure it was a lot of money. I looked at a tank from a TBI truck, but it won't fit. Any suggestions or opinions are appreciated. Hopefully she's on the road this summer.

As long as its a TBI vehicle you get the tank and and pump/sending-unit from you will be okay. Vortec, or most any kind of multi-port EFI is much higher pressure.

A good tank that fits between the frame rails is a 88-95 cab & chassis tank. Its only 10" wide or so and holds 22 gallons. Here's a pic:

If you don't mind a rear-mounted tank, you can also expand your search to include Jeep tanks - most use a similar TBI system. I've used a 33-gallon K5 Blazer tank on my 91 crewcab, and I'll be installing one in my '66 C10 as well.

Hey Jeff C, I bought a '95 TBI engine with harness and computer and auto transmission that I was considering in putting in a '57 P.U. Did you use the original harness and computer? If so, did you have any problems?

Hey Seon. When the guys at thr wrecker pulled the engine for me, they knew it was goin' in a hotrod, so they disconnected as few things as possible. The engine, with computer and wiring was all one package, so it's just a matter of dropping it in, putting your computer where you want it, and making some sort of organized path for all the wires, which there isn't a whole lot of anyway. I got a 700r4 from an 88-93 pickup so it still has the speedo cable, but there's just a little white plug hanging off the engine wiring harness that plugs in the trans to control the lock up converter. Pretty easy swap altogether. Have fun.

Jeff, thanks for the info. I recently picked up a '01 GMC sportside that was rolled but runs and drives beautifully. I plan to remove the cab and bed but use all the componets i.e. gas tank, steering column, swing pedals, etc, then mount my '57 Burb. Other than shorten the frame about 4", it looks easy enough. Now just to find the time!

Remember that the pump has to sit on the bottom of the tank, or you'll never be able to use the gas in the bottom. Best bet is to use a complete tank, pump and sending unit from a TBI vehicle, or you'll have to shorten/extend the tube that mounts the pump in a way that doesn't mess up the accuracy of the float. GM used the same pump in most if not all TBI vehicles, and the pickup screen is cheap and easy to replace when the pump is out of the tank.

Just a couple of things I learned the hard way!
