Vehicle description: Passenger vehicles built with 3.5L engines. The fuel injection delivery system can leak fuel from some of the sealing O-rings or from hair line cracks in the thermoset fuel injection rail.
Dealers will replace the fuel rail O-rings and reinforce the outlet (passenger) side fuel rail. Vehicles showing fuel leakage on the outlet fuel rail must have the outlet rail replaced which includes changing the upper and lower injector O-rings. However, if a vehicle is leaking fuel from the O-rings or from a cracked fuel line, the vehicle should be taken into a dealer to have this repaired as soon as possible.
