Sooo, doesn't seem like return is restricted, FPR or pump?...

I would think the FPR should hold absolute pressure, no matter pump is 50-100psi, regulator should be to set value(43.5)? Isn't that the point of a regulator ...so FPR bad? I can adjust it and get pressure back up..so not that the pressure isn't available from pump.

Thoughts

2+2=4; 2+0=2; 4>2 : 2+2 > 2+0.
