AJP,

Thanks, and that is exactly the suggestion I got from Gaspar this morning. He is suspecting pump cavitation on the inlet line, so he suggested starting from an external tank direct to the pump, and then start adding back in the shut-off valve, the UAT and the a/c tanks one at a time to see where the problem is.


As this is a brushless pump, the Pw adjustment is not available. It was topping out at around 2600, which indicates differently then the old brushed pump motor Pw readings.


Hopefully I can get a chance to try later in the week.
