Few weeks ago, when the leak/issue was not as bad, we brought the pressure to 3.2 inch and then isolated both the hogger and jets. Then we let the pressure rise to 3.8 in and we timed it. It took 90 sec. Per OEM this should take 20 minutes.
The other test was I had the jets and the hogger run in parallel and we still could not get the pressure to go down. Then we had the hogger on manual with all the jets isolated manually and the hogger didn’t bring the pressure down to the spec which we used to get to 3.5 in.
