Pat, I was an English major, so I look at the language first! ;-)
BTW: The Control Pressure tests in the Bentley are done with a running engine. The test in the Porsche K-Jetronic Workshop Manual is done with the engine off. The manual also states that engine temp is “not important.”
Tony,
I installed a new battery in the car and re-tested the fuel pressures. No significant changes.
System Presssure (specification is 65 – 75 psi): My reading = 68 psi
Cold Control Pressure: (temperature 27 C, so specification is 25 – 30 psi): My reading 20 psi
Warm Control Pressure: (specification after 3 – 5 minutes, 39 – 46 psi): My reading 32 psi
New battery static voltage just under 13 v
Voltage to the WUR = 10.96
Should I conclude from this that the WUR needs adjustment or is there something else to check?
Lastly, IF a new fuel pump delivered 75 psi how would that effect the cold and warm Control Pressures?
Oh, and I forgot to answer your question, my WUR is a 045.
Hope you're enjoying the weekend!
