I recently changed to PMO carbs. I have the PMO fuel pressure regulator which calls for the use of the fuel return line. I previously had used a Carter inline pump and did not have the return line hooked up.

I am installing new metal fuel lines from tangerine. I figure that if I am replacing lines, I might as well replace the return line also (even if I don’t use it).

My question is- can I use the same carters inline pump and also use the fuel return line or do I have to get a fuel pump that has a return port? I have never used a fuel return line so I have a poor understanding of its function- I am not clear if any sort of pump pressure is needed to get the fuel to return?

The return comes off of PMO regulator.
One in from pump, one out (return) and two to the carbs, one for each carb.

So do I run the line directly from the pmo regulator up front to the fuel tank?

Interested in a mount for the PMO regulator?

Needs no holes drilled into the car. Easy to see the gauge and adjust the pressure.
I'm thinking $35 shipping included.

I'll post some pics later tonight.
