Removal Procedure
There are two types of quick-connects used on fuel pipes. The plastic collar type does not use any special tools for removal. The metal collar type uses J 37088-A Fuel Line Quick-Connect Separator. Refer to Metal Collar Quick Connect Fitting Service to service metal collar-quick connects fittings.
Caution: Relieve the fuel system pressure before servicing fuel system components in order to reduce the risk of fire and personal injury.
After relieving the system pressure, a small amount of fuel may be released when servicing the fuel lines or connections. In order to reduce the chance of personal injury, cover the regulator and the fuel line fittings with a shop towel before disconnecting. This will catch any fuel that may leak out. Place the towel in an approved container when the disconnection is complete.Caution: Place a dry chemical (Class B) fire extinguisher nearby before performing any on-vehicle service procedures. Failure to follow these precautions may result in personal injury.
- Relieve the fuel system pressure. Refer to Fuel Pressure Relief .
- Grasp both sides of the quick-connect fitting to prepare the quick-connect fitting for removal. Twist quick-connect fitting ¼ turn in each direction to loosen any dirt within fitting.
- Repeat for other fuel pipe fitting.
- Blow out dirt from quick-connect fittings at both ends, using compressed air.
- Remove the retainer clips on the quick-connect if applicable.
- Squeeze plastic tabs of male end connector.
- Pull connection apart.
- Wipe off the male pipe end using a clean shop towel.
- Clean or replace components/assemblies as required.
Caution: Wear safety glasses when using compressed air in order to prevent eye injury.
Repeat for the other fitting.
Installation Procedure
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.- Apply a few drops of clean oil to the male pipe end.
- Push both sides of the quick-connect fitting together in order to cause the retaining tabs/fingers to snap into place.
- Pull on both sides of the quick connect fitting in order to make sure the connection is secure.
- Install the retainer clips on the quick-connect if applicable.
- Connect the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection in Engine Electrical.
- Inspect for fuel leaks.
- Install the intake manifold sight shield (1) to the engine.
- Install the intake manifold sight shield nuts (2).
- Install the rear seat cushion. Refer to Rear Seat Cushion Replacement in Seats.

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.
Tighten
Tighten the intake manifold sight shield nuts to 3 N·m
(27 lb in).
