Hi, I have been working on a 1989 Camaro with a mildy aggressive 350 that has a 600CFM Performer Edelbrock carb on it.

I have been having two problems with this car that I can't seem to track down:

1. The engine has trouble starting after it has been running for awhile. It seems like it always floods because the only way to get it to fire is by holding the pedal all the way to the floor which still takes 5 or more cranks.

2. The car has the electric fuel pump from the 2.8 setup instead of a mechanical pump on the block. It is brand new and I have a fuel pressure gauge before the regulator, which reads zero while the pump is running. After the regulator I have another gauge which reads 3 PSI, no matter what the adjuster screw is put at. When I clamp the return line from the regulator with a vice grip, I get a pressure reading of ~10psi on the gauge before the regulator. This also makes the adjustment screw change the pressure reading on the gauge after the regulator.

Anyone have any insight on this issue? Help would be much appreciated on this since it has been stumping me for awhile.

Sounds like you've got the supply and return lines from the pump swapped at the regulator.

Disconnect ALL the lines from the reg. Put em all to where they'll spew into a bucket or something safe like that. Turn the key on. Whichever one fuel spews out of, that goes to the regulator "in".

After that, how you should hook up the rest of it, depends on what regulator you have.

Thanks for the reply, but I should have mentioned that I already did that. The one I have going to the "In" is the one that spewed fuel when I turned the key on.
