Been doing some more reading.
Apparently if there's and kind of restriction in the return line, such as tight corners, joining different pipe sizes (which I have ) and other stuff, the fuel pump can overpower the Boost FPR
What can I do?
Replace with larger diameter pipe? If so where from?
Could I just use rubber all the way thru?
Also read that might be better placing the boost FPR by the tank to rule out any of these problems
Heres the FPR

But then I'd have to run air line to the fuel tank
Any suggestions?
