    im trying to mount an efi fuel pump (out of '98 camaro) in the old fuel tank ('77 K20), the openings are different, i was going to "move" the new opening but that requires metal working skills i don't really have.

    so i could go new tank with custom opening, anyone make those? the cheaper the better, and has to have at least close to original capacity, and don't want to mount it in the bead, got other plans for that space.
    or should i give up and get an external pump, which i really don't want to do since i already have the camaro pump and all the lines.

    Are you going to an EFI setup? If you are then I would get a holley inline fuel pump because you will have to get a custom tank made to work for that camaro pump. If you are staying carbed than why do you wan't an electric pump? You would just have to put a regulator on it and bring it down from 30 something psi to around 5psi. I would stick with a mechanical pump if you are staying carbed.

    I run a carb with an electric pump. As long as you get one for a carb engine no regulator is needed.

    DO YOU NEED ONE OUT OF THE CAMARO FOR A SPECIEL REASON ?
    JUST GET A TANK OUT OF A 87-91 SUBURBAN (31 GALLON NOT THE 40 GAL)OR BLAZER, GET TANK AND PUMP
    SHOULD WORK GOOD ?

    sorry, takes me a while to respond, im on here once every 24/48 hours, work permitting.

    that fuel pump puts out enough preassure for a 58psi reg., so its got some kick, and yes im going EFI, thats the sole purpose for the pump, i have a 98 camaro motor under the hood (LS1 inside /forums/images/graemlins/grin.gif ) and now i need to feed it.

    would the suburban tank have the right kind of opening? 87-91 were still carbed days, weren't they? and i need one to fit a pick up, so one out of a K5 wouldn't work, isn't a burban tank like a K5 tank?

    You'll need the tank out of an 87-91 pick-up. You'll need the sender too.

    Essentially plug and play, you might have to screw with the pump a bit to make it fit the TBI sender, but it's not hard. Grab all the fuel pump wiring from the donor that you can as well. BTDT.

    87 P/U is the first year for EFI. I looked in the Mitchell Collision Estimating Guide Domestic. They say all Fuel tanks both 16 and 20 gallon tanks are the same for C/K 78-86 and R/V 87-91.. Just should need to get a 87-91 Pump.

    Is this in your 4X4? Aren't you afraid of the water on the front of the engine where the Distributer is? You did say a LS1. I was thinking about the LT1, just don't know about the distributer....

    Not intending to hijack or anything, but are you serious that the 40 gallon pump won't work in the 31 gallon tank? If that's true my TBI swap is going to be put off even longer than it already is... I thought the 40 gallon tank was just a little longer, not deeper. Hopefully someone can shed some light on this...

    I checked on one I pulled out of a 40 gallon tank, and it was EXACTLY the same as the 31 gallon sender. GM parts manual said they were different, and I can't vouch that the one I pulled was original to that tank, but it was identical. No reason it shouldn't have been, unless the 40 gallon tanks are different, which I don't believe is the case.
