Just wondering what the life expectancy of my fuel pump is, or when I can expect to change it. The last 1990 ford I had, it was ever 75,000 miles, just like clock work. I now have a 2004 Crew Cab 4 X 4 F-150 with the 5.0, with 127,000 miles.
Thanks,
Matt

 

Probably water or contaminants mostly detriments. Look to the fuel pump module for corrosion first and set it up off the frame after cleaning and sealing the back side.
