Am i right i saying that a pair ot twin 40s on a pinto does not have a fuel return pipe.
Changing over from a twin choke and there does not appear to be a place for one.

No return mate. Normally only a return on injection systems.

Brother in law runs 45's on his xe and no return pipe. He uses a fuel pressure reg and an electric redtop( At least I think it is from memory) pump

lots of the twin chokes had a return DGAV DGAS but not needed on DCOEs. just block it off.

Cheers all, one less thing to worry about.
