1996 Chevrolet Tahoe 2 wheel drive 4 door 5. 7 vortec fuel pump failure. I have replaced the fuel pump assembly 3 times in the last 45,000 miles(4 months)the wiring connector to the pump gets hot and melts the wires inside the pump the last one had melted the wire bare inside the tank. The pump still works but the pump assembly is unusable due to melting of the housing and resulting leakage.
Replaced fuel pump on 7/27/02. Fuel pump failed due to electrical problems again on 7/28/02. Electrical connection to pump replaced and 2nd replacement pump installed on 7/30/02. Total cost of repairs $665. 58. Safety recall TSB #98044, Aug. 98 "fuel tank" - may contact body sill. I don't know if this was ever corrected on my vehicle. I am the second owner. It is possible that this recall was the cause of the problems with my vehicle.
