Inliners International Forums General Discussion Blown and Injected Hacking together EFI on an Pontiac OHC Six

Made the fuel rail and hold downs today. Same method as last time, ran a 3/8" pilot hole into the fuel passage, followed up with the 17/32" bit but stopping a bit short of the fuel passage. Then used a dremel to bevel the opening followed by some fine grit (400?) sand paper, red scotch brite then green scotch brite. Tapped threads into the ends for the fuel fittings and then cleaned it and cleaned it.
