The problem has been going on for 1-½ months.
The carb vent is clear.
I'm ordering the Canton fuel pump insulator from Jegs, and the fuel filter with a return provision from Pontiac Tri-Power.

Regarding the return line, do you recommend buying a pre-bent one, or bending my own? The Right Stuff has a pre-bent one, but I have no experience with those.
Going for a test drive now...
