Hi...

Hope some of you nice folks will help a fellow out.

Motor: SBC 350
Year: Block 78, Heads 80 something.
Carb: Edelbrock 1406, about a year and a half old.
Fuel Pump: Electric.

Problem:
1. Fuel coming out of carb at linkage points on auto choke side.
2. Fuel draining back to tank when key not on.
3. When key is in the on position, fuel pressure reads only 3 PSI,
but I have it set to 4 PSI. On the occasions that the problem does NOT show itself, fuel gage shows the correct 4 PSI.

Other info:
Have high pressure fuel pressure regulator set at 4 PSI.
Exhibits problem, 90% of time now.
Backfired a few times.
Hard starting.
If I take the fuel line off carb and plug it, (have sight glass filter) gas DOES NOT drain back to tank.

Please ask for more info if needed.

Thank you,
John
