Thread: EFI Tank Fuel Pump Holes Do Not Align

  1. #1

    Default EFI Tank Fuel Pump Holes Do Not Align

    I purchased a Holley EFI Sniper conversion fuel tank which is a Tanks Inc fuel tank. My problem is the mounting holes for the fuel pump to the gas tank are way off and do not align one bit. I don't want to make new holes or make the new holes bigger due to sealing issues. Just wondering if anybody has had problems with this. Thanks.

    I tried to contact Tanks Inc, but I'll contact Holley. Thanks.

    Just got off the phone with them and they said I need to return everything and get a replacement, as they've never heard of this happening. They don't know which part is bad the gas tank or the sending unit or fuel pump. (The Holley EFI fuel tanks are made by Tanks Inc. There's a nice Tanks Inc stamped on the fuel tank.)

    I'm gonna try again. This is from Tank Incs website:
    Sender Bolt Pattern & Swing
    Our tanks are setup for the standard SAE 5-hole bolt pattern used by all of the aftermarket gauge manufacturers. The 5-holes are not evenly spaced. Two of the holes are farther apart than the other holes. If you are holding the sender with those two holes closest to your body, the hole directly across is known as the index hole. If the float swings to the right, it's a right-swing sender. If it swings to the left, it's a left-swing sender.

    Yeah, that seems like the problem.

    I was able to figure it out. The main problem with the fuel pump, was the manufacturer put the hose clamp to close to the top, therefore not allowing the mount to seat all the way. So I loosened the clamp and lowered it a little bit, now it's perfect. And in post #3, that was the problem. Easiest way is to line up the gasket first with the holes and mark the gasket. Then line up the gasket with the sending unit and mark it. But I did manage to mess up my ground wire and have a little wire exposed. Do you think I need to make a new ground wire, or will heat shrink or electrical tape work to wrap it?

    Yes.

    No, not inside the fuel tank.
