How long do you keep your trucks ? Take it from a long time Chevey driver about 85,000 miles the in tank fuel pump is going to be replaced and in a pickup the best way to change a fuel pump is to slide the bed back.My 96 had 3 replacement fuel pumps.The factory pump lasted 87,000 and the other 3 were put on between 87,000 and 109,000.Knowing that and after spending hours unloading the pickup I would think looooooooong and haaaaaaaard about working out of a pickup/toper setup
