Summary

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.
