There are two types of quick-connects used on fuel pipes. The metal-collar type uses J 37088-A Fuel Line Separator for removal. The plastic-collar type does not use any special tools for removal. Refer to Plastic Collar Quick Connect Fitting Service to service plastic quick-connect fittings.

1. Relieve the fuel system pressure. Refer to Fuel Pressure Relief .
2. Remove the retainers from the quick-connect fitting.



3. Grasp both sides of the fitting. Twist the female connector ¼ turn in each direction to loosen any dirt within the fitting.




Caution: Wear safety glasses when using compressed air, as flying dirt particles may cause eye injury.

4. Blow dirt out of the fitting using compressed air.



5. Choose the correct tool from J 37088-A Tool Set for the size of the fitting. Insert the tool into the female connector, then push inward to release the locking tabs.



6. Pull the connection apart.

Notice: If necessary, remove rust or burrs from the fuel pipes with an emery cloth. Use a radial motion with the fuel pipe end in order to prevent damage to the O-ring sealing surface. Use a clean shop towel in order to wipe off the male tube ends. Inspect all the connections for dirt and burrs. Clean or replace the components and assemblies as required.

7. Using a clean shop towel, wipe off the male pipe end.
8. Inspect both ends of the fitting for dirt and burrs. Clean or replace the components as required.

Caution: In order to reduce the risk of fire and personal injury, before connecting fuel pipe fittings, always apply a few drops of clean engine oil to the male pipe ends.

This will ensure proper reconnection and prevent a possible fuel leak.
During normal operation, the O-rings located in the female connector will swell and may prevent proper reconnection if not lubricated.
1. Apply a few drops of clean engine oil to the male pipe end.



2. Push both sides of the fitting together to cause the retaining tabs to snap into place.



3. Once installed, pull on both sides of the fitting to make sure the connection is secure.
4. Install the retainers from the quick-connect fitting.
5. Reconnect the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection in Engine Electrical.
6. Inspect for fuel leaks.

6.1.	Turn the ignition switch On for 2 seconds.

6.2.	Turn the ignition switch OFF for 10 seconds.

6.3.	Turn the ignition switch On.

6.4.	Check for fuel leaks.




7. Install the intake manifold sight shield (1) to the engine.

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.

8. Install the intake manifold sight shield nuts (2).

Tighten
Tighten the nuts to 3 N·m (27 lb in).

9. Install the rear seat cushion. Refer to Rear Seat Cushion Replacement in Seats.
