first of all, the port size is 3/8"NPT, and the regulator is one "in" port and two "out" ports.
secondly, the part number is 12-803. according to the instructions, if this was a return regulator, the part number would be 12-803BP [bi-pass].
so i need to go regulator shopping.
it looks like the aeromotive pump will do what i want it to, thanks to those that have responded with their personal experiences. up
i now have a 3/8" feed line, but i think i will remove that and go to 1/2", since i have to fab a return anyway.
i was thinking of plumbing the return into the filler neck just before it goes into the tank. is that an ok choice ?
beer

I would not put it in the filler tube, fuel will be going all over the place inside the tube, & if you ever opened the fuel cap with the pump on I bet fuel would blow out all over you & the car. the vent at the top of the neck would also be compromised & leak out raw fuel. just my two cents
