2011 GMC Sierra 1500 fuel system problems

FUEL/PROPULSION SYSTEM

Over the past few years squirrels have eaten through the fuel line of the truck just above the fuel tank multiple times. As soon as the ignition switch is turned on fuel gets pumped out very near the exhaust system. The driver may not notice anything wrong immediately causing a very real fire risk. Today is the fourth time I have experienced this issue with this truck.

FUEL/PROPULSION SYSTEM

DUE TO A FAULTY DESIGN AND OR MATERIALS USED THE FUEL PUMP MODULE ASSEMBLY LOCATED ON THE TOP OF THE TANK HAS PREMATURELY CORRODED AND CAUSED A DANGEROUS SITUATION WITH POTENTIAL THREAT TO LIFE AS WELL AS CONTAMINATING THE ENVIRONMENT. GAS IS LEAKED OUT OF THE UNIT AND CAN BECOME VERY DANGEROUS IF UNNOTICED OR NOT REPAIRED. VEHICLE WAS PURCHASED NEW IN 2012 AND HAS ONLY SEEN 4 WINTERS. MECHANICS AT THE GARAGE STATED IT WAS A COMMON OCCURRENCE THEY HAD SEEN IN NUMEROUS VEHICLES AND CAUSED BY A POOR DESIGN IN WHICH SNOW AND SALT CAN ACCUMULATE ON TOP OF THE TANK RATTING THE UNIT AND GAS LINES PREMATURELY. I CONTACTED THE MANUFACTURER AND THEY WERE NOT CONCERNED AND CONSIDERED IT "NORMAL" WEAR AND WAS AN UNFORTUNATE SITUATION. GAS LEAKS WHEN STATIONARY AND IS LEAKED WHEN SYSTEM IS PRESSURIZED SPRAYING THE UNDERCARRIAGE OF THE VEHICLE AND A MAJOR CONCERN FOR POTENTIAL FIRE OR EXPLOSION WHEN GASOLINE IS VAPORIZED.
