J 37088-A Fuel Line Quick-Connect Tools

Notice: Cap the fittings and plug the holes when servicing the fuel system in order to prevent dirt and other contaminants from entering the open pipes and passages.

Important: Always maintain cleanliness when servicing the fuel system components.

Important: There is no service interval for an in-line fuel filter replacement. Only replace the in-line fuel filter if the filter is restricted.

1. Relieve the fuel system pressure. Refer to Fuel Pressure Relief .

Caution: Provide additional support when a vehicle is on a hoist:

•	Before removing parts, support the opposite end. This helps prevent the vehicle from slipping off.

•	Before removing major components, chain the vehicle frame to the hoist pads at the same end as the removal. This helps avoid a tip-off.

Failure to follow these precautions could cause vehicle damage, serious personal injury, or death.
2. Raise the vehicle.
3. Disconnect the quick-connect fitting at the inlet of the in-line fuel filter. Refer to Plastic Collar Quick Connect Fitting Service .
4. Disconnect the threaded fitting at the outlet of the in-line fuel filter.
5. Drain any remaining fuel into an approved gasoline container.



6. Remove the in-line fuel filter assembly attaching bolt and remove the fuel filter assembly.
7. Remove the in-line fuel filter from the mounting bracket.

Notice: Always re-attach the fuel lines and fuel filter with all original type fasteners and hardware.

1. Remove the protective caps from the new in-line fuel filter.
2. Slide the in-line fuel filter into the mounting bracket.
3. Install the in-line fuel filter and the mounting bracket.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

4. Install the bolt that retains the in-line fuel filter mounting bracket.
