Called the dealership the other day to ask how much for fuel pressure test. The servive manager said he will charge me $75 if they test it and I choose not to let them do the work. If they test it and then need to replace the lift pump then the charge will go on a normal labor ticket. When I asked if he covers the lift pump under warranty he said that depends on the VIN. How much are you guys paying to have yours tested? My truck has 53,000 mi. on it now and at times I feel like I am loosing power at higher rpms. Changed fuel filter about 1000 miles ago.
