SOME PASSENGER VEHICLES EQUIPPED WITH 4.0L V8 ENGINES HAVE A CONDITION IN WHICH THE NYLON TUBING USED IN THE FUEL RAIL CONSTRUCTION MAY DEGRADE AND CRACK. ADDITIONALLY, THE 1995 MODEL YEAR USES A UNIQUE UNDERHOOD FUEL RETURN LINE THAT MAY CRACK. CRACKING OF THE FUEL RAIL OR RETURN LINE TUBING CAN RESULT IN A FUEL LEAK INTO THE ENGINE COMPARTMENT.
THESE VEHICLES COULD HAVE BEEN PRODUCED WITH AN IMPROPERLY ADJUSTED SECONDARY HOOD LATCH. THIS DOES NOT CONFORM TO THE REQUIREMENTS OF FMVSS NO. 113, "HOOD LATCH SYSTEM."
Whether a recall was fixed on a particular car is known only to the manufacturer: check the VIN at nhtsa.gov/recalls.
