Re: LS gas tank for 65?

On a recent EFI conversion, I ran a low pressure pump out of the tank to a surge tank, which fed an external high pressure pump. Return goes back into the surge tank, and overflow goes back into the fuel tank.

Advantage #1: You're not cutting up an original gas tank, or compromising the internal coatings.

Advantage #2: You can run on almost fumes, and never starve the high pressure pump of fuel.

Disadvantage: Complexity.
