Please excuse me if I am confused, but it seems to me considering your tests results showing low fuel flow and bubbles in the fuel line going from the fuel distributor ( the circuit that exerts pressure on top of fuel distributor plunger) - to the wur that, if in fact it is below spec., would lead me to think that there could possibly be another problem in addition to the wur problem, since your video shows this issue prior to the wur. I do not know what the "normal" fuel volume should be at this point in the circuit so I am just raising the question.

Dave,
Your observation is correct. There is a likelihood that there could be another restriction point down stream. To confirm the the absence of flow restriction, the OP needs a good pressure gauge kit in the first place. The S&G 33800 gauge is a very reliable pressure gauge kit and I have 3 of them. It is imperative that Joe finds a good set of gauge to do the testing.
The good news is the the FD is in excellent condition with remarkable identical flow rates. I will send a WUR-090 loaner that he could try in his car as soon as I get them to pass the calibration tests. I am in contact with Joe and discussed the strategy. Thanks.
Tony
