Re: TOP END REFINISHING
Ok - I had (relatively sure hereof) a blocked OPEN check valve in the tank.
Test:
Both fuses in.
Power to test terminal.
Pinch feed line BEFORE rails inlet.
Power off test terminal. Pressure held @ 52.
Release pinch on rail feed inlet. Pressure dropped IMMEDIATELY ~12 to 40.*
Test again, NO PINCH, 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 [obstruction / sticking check valve] back OUT OF IN-TANK CHECK VALVE.
Could this be ANYthing else???????
