I would work extra hard at whatever I was doing to become so good at it and that I would never have to kiss anyone's fanny to keep my job. And I never have and I never will.

Would the manual valve not need to be on the supply line to test the check valve?

Hi, waiting for me? The answer to your question is you put a valve AFTER the fuel pump in the supply line to test the check valve. As for testing for bursting pressure, you would shut the pump off first and then close the valve. To test the PPR you would put the valve in the return line (I may have mixed them up in a previous post, oops). Again, you would shut the valve only after you shut the pump off. In another thread the poster used a "C" clamp. Not as elegant but you do not have to undo any connections. As long as you know you have sufficiently blocked the line so it is not leaking and you don't collapse it. IMHO it is rare to have a problem with the PPR unless you have changed the original "O" rings. Much more likely the check valve is the problem. Even if it has been replaced!
