Dealer Service Instructions for:

Safety Recall Y10 / NHTSA 21V-665 Fuel Supply Line

 

Remedy Available

2020 (JL) Jeep Wrangler

 

NOTE:  This campaign applies only to the above vehicles equipped with a 2.0L engine (sales codes EC1 and EC3).

 

NOTE:  Some vehicles above may have been identified as not involved in this campaign and therefore have been excluded from this campaign.

 

IMPORTANT:  Some of the involved vehicles may be in dealer new vehicle inventory.  Federal law requires you to complete this recall service on these  vehicles before retail delivery.  Dealers should also consider this requirement to apply to used vehicle inventory and should perform this recall on vehicles in for service.  Involved vehicles can be determined by using the VIP inquiry process.

 

Subject

The fuel supply line connector on about 14,400 of the above vehicles may crack.

Uncontained gasoline in the engine compartment can result in a vehicle fire which increases the risk of injury to occupants and persons outside the vehicle, as well as property damage.

 

Repair

Locate the fuel supply line that feeds into the high pressure fuel pump on the engine. Inspect the date code on the fuel line tag. If the date falls within the specified range, replace the line.

If the tag is missing, replace the line.

 

Alternate Transportation

Dealers should attempt to minimize customer inconvenience by placing the owner in a loaner vehicle if inspection determines that fuel supply line replacement is required and the vehicle must be held overnight.

Service Procedure

WARNING: Observe the following precautions when working on fuel systems: No sparks, open flames or smoking. Avoid inhaling and swallowing fuel. Avoid eye and skin contact with fuel. Pour fuels only into suitable and appropriately marked containers. Wear protective clothing. Failure to observe these precautions may result in fire, explosion, property damage, and serious or fatal injury.

 

WARNING: The fuel system is under constant pressure even with engine off. Before servicing the fuel rail, fuel system pressure must be released.

 

NOTE: The “Fuel Adaptive Parameter Reset” and “Fuel Feed System Component Replacement” scan tool procedures should always be run after a PCM, fuel injector, fuel rail, high pressure pump or fuel pressure sensor is replaced. The procedures should be in the “Miscellaneous Functions” tab in the PCM. Failure to run the procedures may cause DTCs to set in the PCM.
