There may be inadequate clearance between the fuel line and the cab underbody. Contact between the fuel line and the underbody could wear the fuel line and cause a fuel leak. Leaking fuel increases the risk of a fire. Dealers will inspect for proper fuel line clearance. Fuel lines with inadequate clearance will be replaced with the redesigned fuel line.

THIS CONTACT CAN RESULT IN WEAR, AND AFTER EXTENDED CONTACT, COULD CAUSE A PERFORATION IN THE FUEL LINE, RESULTING IN LEAKAGE. FUEL LEAKAGE IN THE PRESENCE OF AN IGNITION SOURCE COULD RESULT IN A FIRE.
