Problem: On certain medium duty trucks equipped with 8.1 l engines and left hand or dual fuel tanks, some of these vehicles have a condition where the fuel filter-to-component box mounting bolts are reversed. With the bolts reversed, the threaded bolt end is oriented toward the front wall of the left hand fuel tank.

WITH THE BOLTS REVERSED, THE THREADED BOLT END IS ORIENTED TOWARD THE FRONT WALL OF THE LEFT HAND FUEL TANK.
Risk: In the event of a frontal crash, the threaded end of the bolts could pierce the front wall of the fuel tank resulting in flue leakage. If an ignition source were present, fuel leakage could result in a vehicle fire.
