When one removes the crossover
When one removes the crossover line, one has to get a shorter banjo bolt. The original one is long to accomodate "2" banjo fittings.........one of which is the crossover line. I used a short 14mm head bolt from the TR FD!!!!!!!!!! Well, it worked.
I only did the right side:
Primary Pressure = 5.5 bar
Cold WUR Pressure = 0.6 bar, with electrical connector off.
Warm WUR Pressure = 2.8 bar, after about 5-7 minutes, with the electrical connector attached.
When I applied some vacuum to the base line, the warm WUR pressure rose to 3.5........release of pressure and it fell to 2.8. I didn't measure the vacuum, but more applied and the pressure went beyond 3.5 bar. There is a larger line, which lowers the control pressure when vacuum is applied..........? The larger line comes off the top of the WUR, and the smaller diameter line comes off the base of the WUR........purpose of these lines?
Turning off the pump, the primary pressure dropped to 3.2 bar, and stayed there.......3.1 after 10 minutes.
I had the fuel injection lines disconnected from the fuel injectors and saw no leaks.
Keep in mind that I was not able to start the car from a cold sitting.
BTW: Ambient air temperature is 39 degrees F. I have read that the colder the air, the lower the cold control pressure........thus a reading of 0.6 bar.......does this seem a little low?
