There are no internal fuel leaks, this is why it has stumped me on this one.
I have all the cummins fuel system testing tooling for these XPI systems.

Then the next test is to see how much fuel is going back to the return lines. I think cummins has a test for this to see if there is too much being returned. I think that fault is associated with that if
I am not mistaken.
