Tested fuel pressure out on the WUR. Why? So that I can get some understanding how parts operate in this system. I also measure fuel pressure after the filter so I had a base line for comparison.
Final pressure tests of both input and return lines at the WUR…..the same. Same as the main fuel pressure off of the pumps…..around 8.75 bar. Well, at least I have pressure.
1). Reduce pressure to the FH or in the FH
There are no shims in the main valve needle fuel feed. I added additional copper washers to the main fuel feed retaining bolt. A little reduction, but not a lot.
Do I install a valve between the fuel filter and the FH to adjust the pressure down?
Going to attempt to start up the motor tonite and closely monitor.
