2). Separate the upper and lower sections. You will find a spring, a cup or “sombrero” and a pin. Remove and save them. You don’t need them for the test.
3). Assemble back the upper and lower sections together. Make sure you put them together the same way they were before. You will notice if they were put together differently. Install back the 4 screws and nuts.
4). Install the WUR back on the car and connect the fuel lines. Do not connect the electrical plug to the WUR. Test run the fuel pump and record the new cold control fuel pressure.
Do not worry about the WUR, I will show you a step by step procedures with pictures for the assembly in case you need them. This particular test will demonstrate the flow restriction if any in your system.
If you have any question or concern, let us know or PM me. Keep us posted. Thanks.

Hey Tony,
thanks for the good advice!!!! I'm really thankful to this forum.
I have send the WUR to checking ang calibration. I will build a connection to check the pressure if the fuel lines make any blocking...
I replaced all the fuel lines and build them myself by DIN 73378 polyamide tubes. cleaned them carfeully with air.. but yeah i know, everything can happen....
Regards Phil
