    what i'm doing with my caddy is using the late corvette filter which has return built in so i just need to run a return line from the filter to the tank, not even 3 feet. then just a single line up to the fuel rail.

    I have done exactly what he has, and dont recommend it. If you are converting to EFI the fuel system needs to be right on the money or drivability problems will occur. It caused air to enter the pump at weird times and ruined my pump. I dropped the tank removed the screen from the pickup installed an inline filter and plumbed the return to the top of the tank, not as much of a pain as it sounds, but well worth it.
