Oh well, I ordered the Walbro 392, 255 lpm. It will probably be overkill for the 5.3 Stock. Looking for the part number for the flexible fuel line for a corvette with 2 quick connects like on Stu Cools studebaker intake. Anybody.? Stu there? Also, I'm looking at running this pump on the frame below the in cab tank in my 68 C20. I'm putting a cannister fuel filter before it with the Corvette FPR after. Anybody see any problems with running a filter before pump? Also running return line back to sender and into tank. Thanks.
