Just replaced the FPR in my 05. Just wanted to thank all that replied and sent info. It actually wasn't that bad of a job to do. I didn't have to disconnect half of what the intruction said to do. I just went after the FPR and removed what was necessary. I also used a 3 inch torx bit and a 1/4 wrench to remove the FPR screws. I ran a magnet across the tip of the bit which helped hold the bit in place as well as extract the screws which also helped to intall them. It took about 3 hours start to finish. The truck runs much smoother. Thanks again.

How much for a new FPVR ?

I bought mine from Oregon Fuel Injection not from the dealer. With shipping I spent $180.00

Yes wicked diesel sells one for like $175 or something, same price as a replacement IIRC. Since you have EFI live you can make it work using table b1010.
