Need replacement FPR?

Where is your FPR located? Aren't they supposed to be in the return line?

Update, pump replaced... now getting 70 PSI with flow obstructed.

Still getting 0 PSI on return side.

The FPR is located on end of the secondary fuel rail where the fuel return should begin.

I am now getting a trickle of fuel out of the pressure relief valve on my tester when testing the return side... I think my original theory is still the problem, I just happened to catch the pump on its way out too.
