High Pressure Pump O-rings
Anybody else going through these O-rings like crazy? Got an 02 7.3 with 54K and I've replaced 3 of the damn things already. I have a Hypertech programmer on 50hp setting, not sure if it makes more pressure in the pump causing the blow-outs. I read about the crossover lines and was wondering if that would fix the problem.
Any info would be great.

I've heard there is problem with the HPOP having hairline cracks in them that O-rings may hold for awhile. With only 54k on the clock, I'd let the dealer look at at it and possibly have the HPOP changed under warranty fo the $100 deductible. A programmer will not cause the HPOP to exceed its limits on pressure. The IPR will limit the high pressure mechanically. A HPX line will help to even out the pressure to injectors, but will not help with this problem.
