FPR

I just put in the FPR shim on my powerstroke, couldnt get my gauge to match up at the time of install, so I had no idea of the before or after fuel pressures. what are the chances of over-pressuring the fuel system? what kind of increase would doing this cause?

Mechanical fuel pump failure ...based on your posted mileage for one.....

so only one or two days of having this FPR shim in and I take it out. never had issues with the truck except this morning when it started to run like crap, check engine light comes on, and died on me. Immediatley removed the shim and it ran just fine. oh well, if its not broke dont fix it I guess.
