I'm going to get my 4th fuel pump installed (in 2 years). Why is my 1999 gmc yukon 5.7 4x4 going through these things like they were snacks??
Also might want to check the voltage at the pump, and check if the tank has a lot of trash in it.are you running the tank down to empty on every tank? The only thing I could think of is that it's overheating majorly. Either that, or there may be a blockage downstream of the pump that's causing excess stress on it to move the fuel along...
