Something that was not mentioned , is that these trucks need at least a quarter tank of fuel all of the time to cool the fuel pump properly . If you are in Arabia (hot) and you are in the habit of running the tank to empty , the fuel pump will overheat . As mentioned ... some of the after market pumps do let go rather quickly and I have seen them fail in 1 to 3 months . I like Delphi brand pumps and have good luck with those .It's my understanding Delphi is a little better than AC Delco even though they are source related. I have also been told Ac Delco builds a higher spec pump that the dealers get and those pumps last longer than the ones consumers get ... again so I have been told.
