Release pinch on rail feed inlet. Pressure dropped IMMEDIATELY ~12 to 40.*
Test again, NO PINCH, then power off.
Pressure dropped VERY SLOWLY:
0:15 = 48
0:30 = 47
0:45 = 47
1:00 = 47
2:00 = 46
5:00 = 45
* This QUICK reverse flow MUST HAVE pushed SOMEthing back OUT OF IN-TANK CHECK VALVE.
OR
UN-stuck it, to free range of motion of the check valve...
Could this be ANYthing else???????
