Hi Team,
Dropped past car to check further as per requests.
Checked Voltage at WUR plug is 0.1v, definitely not 12v. 100% have 11.5v at plug end when FP is running.
Ran tests again with Vacuum of 15Hg, Ambient 12.5 Deg Celsius
CCP 18.5 PSI/ 1.3 Bar
WCP Same as above, ran for 9mins no change.
When I turn fuel pump off gauge rises to 2.0Bar, don't think this means anything?
Attached a couple of images showing my system hook up and the gauge with Vacuum applied.
