thanks for answering my question Rich !
the fuel system i'm putting in my charger is being designed for FI down the road, although when i get it running again, it will be carbed.
i now have a 3/8" feed, and i'm going to bend up a 1/2" return.
i just purchased an aeromotive 340LPH pump, so the next move is a regulator, hopefully one that has high and low pressure capabilities so i don't have to buy it again.
