Odds are this is the case.

My sources tell me that most anything military (hard parts) gets pretty much wiped out in service requiring lots of parts which is why you got the high price quote.
Ok that's good to know, so I will just have to bite the bullet and do it then.

Would you think this would happen with a cold pump on a test bench and then still produce factory spec injection pressure/volume at higher engine operating RPM?
