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: Remove the fuel tank cap and relieve the fuel system pressure before servicing the fuel system in order to reduce the risk of personal injury. After you relieve the fuel system pressure, a small amount of fuel may be released when servicing the fuel lines, the fuel injection pump, or the connections. In order to reduce the risk of personal injury, cover the fuel system components with a shop towel before disconnection. 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.

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



2. 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.
3. Repeat for other fuel pipe fitting.

Caution: Wear safety glasses when using compressed air in order to prevent eye injury.




4. Blow out dirt from quick-connect fittings at both ends, using compressed air.
5. Remove the retainer clips on the quick-connect if applicable.



6. Squeeze plastic tabs of male end connector.



7. Pull connection apart.

Repeat for the other fitting.

8. Wipe off the male pipe end using a clean shop towel.
9. Clean or replace components/assemblies as required.

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



2. Push both sides of the quick-connect fitting together in order to cause the retaining tabs/fingers to snap into place.



3. Pull on both sides of the quick connect fitting in order to make sure the connection is secure.
4. Install the retainer clips on the quick-connect if applicable.
5. Connect the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection in Engine Electrical.
