Bought fuel pressure gauges and system and cold control pressures are the same (control should be significantly lower). Read that this can mean the WUR is clogged. I did test I found here of opening the WUR outlet line and no fuel comes out (line pressurized and flowing into WUR). I disassembled WUR and the inlet screen looks clear and I can blow into the inlet and outlet lines and air comes out the little holes on interior part of WUR. WUR inlet/outlet seem be connected only by a metal plate with a pin and spring pushing it. Not sure how the hell this thing works or how to test it further? Don't want to replace WUR unless I'm sure that's what is wrong.

Thanks
Sounds like you're following the correct procedures.

One thing to clarify, when you did your test and found no fuel coming from the wur outlet line, are you certain there was fuel coming into the wur from the fuel distributor? You said the system was pressurized but the fuel blockage could be within the fuel distributor since you have confirmed the wur itself is not blocked.

Let us know if you are getting fuel into the wur.
