As does the engine on my parents truck, and my friend's suburban I believe. There is a little regulator on the fuel rail near the inlet, and the schrader valve is on the opposite side of the fuel rail.Quote:
So, you're fuel rail has a pressure AND return line on it? All truck engines I have seen only have a pressure side. I preach the Corvette style regulated fuel filter to everyone and I have yet to hear a single complaint about fuel problems, other than the hose coming off the fuel pump because they used cheap hose or didnt' double clamp the connections. The Corvette fuel filter takes the 3/8" fuel pressure line into the filter and when it exceeds 58lbs returns it back to the tank through the 5/16" line. The opposite side of the filter continues the 3/8" fuel path to the fuel rail and it never sees the fuel tank again.

I had my 350 set up with TBI from a '90, so I left the wiring for the fuel pump, and I had it wired through a kill switch. I'm starting to wonder if the wiring isn't holding the voltage on the pump back, but admittedly I am now grasping at straws.
