Aluminum Fuel Tank Project / EFI Fuel Cooling

Hi, just to add I would put the pickup at the rear of the tank.
Or make a surge tank the sits inside the tank that is fed with a lift pump.

Also the return nipple is smaller than your supply nipple could this add to a flow restriction that could make your pump work harder. I doubt it, but just an idea, as the heat issue could be caused by a collection of problems not just just one big one.

Or perhaps you could go to dual smaller pumps and trigger the second pump to come on when needed?
