I have the WUR backed all the way out, and still cannot get the pressure to drop. not sure I can keep it running for five minutes . LOL
Looking forward to figuring this out.

Jim,
We are just doing a fuel pressure test. No need to run the engine. Are you familiar how to manually test run the FP? I thought you said you have a newly rebuilt FD? Your system pressure is too low. Set it to 72 psi.
Could you post the Bosch ID number for the WUR and FD? Do you have the correct WUR and FD? Keep us posted.
Tony
