TWO TOP MOUNTING STRAPS SECURE THE FUEL TANK TO THE FRAME. BREAKAGE HAS OCCURRED WHERE THE STRAP BOLTS TO THE FRAME RAIL.
Consequence
IF THE STRAP BREAKS, THE FUEL TANK CAN MOVE AND RUB AGAINST THE FLOOR OF THE BODY AND THE FUEL LINES CAN BE DAMAGED.
Remedy
DEALERS WILL INSTALL A STRONGER STRAP REPLACING THE UPPER STRAP. A FRAME CROSSMEMBER/CHANNEL, DESIGNED TO BOLT ONTO THE FRAME LOWER FLANGES DIRECTLY BEHIND THE FUEL TANK, WILL BE INSTALLED WHEN THE CHASSIS DESIGN DID NOT PLACE A FRAME CROSSMEMBER WITHIN 2" MEASURED FROM THE REAR OF THE FUEL TANK.
AN "L" SHAPED BRACKET WELDED TO THE FUEL TANK SUFFERS FROM FATIGUE FAILURE OF THE STRAP WELD TO THE FUEL TANK. WHEN ONE STRAP FAILS, THE TANK WILL ALLOW THE TANK TO MOVE WILL THE VEHICLE IS IN MOTION, CAUSING INCREASED FATIGUE TO OTHER TANK ATTACHMENT WELDS.
Consequence
IF SEVERAL TANK STRAP WELDS FAIL BEFORE CORRECTIVE ACTION CAN BE PERFORMED, THE FUEL TANK CAN SEPARATE FROM THE VEHICLE, CAUSING A ROAD HAZARD.
Remedy
SPRINGS AT THE FOUR LOWER STRAP MOUNT CONNECTIONS TO THE LOWER FRAME HAVE BEEN POSITIONED TO COMPENSATE FOR FRAME MOVEMENT. THESE SPRINGS WILL PROVIDE CONSISTENT STRAP FORCE AROUND THE TANK REGARDLESS OF FRAME MOVEMENT.
