I have just changed the fuel system from a non return style to a return style.
I used #8 To the carb and #6 return and I cannot get more than 3 psi with the regulator adjusted all the way open.

I am using a 140gph pump.

I can get the pressure to rise if I pinch the return line and restrict flow. Is it possible I used too big of a return line or is there another problem.

What would be the best fix?
