Tools Required

J 37088-A Fuel Line Quick-Connect Separator

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

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.

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 fuel system components.

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



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



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



4. 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.



5. 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.

6. Wipe off the male pipe end using a clean shop towel.
7. Inspect both ends of the fitting for dirt and burrs. Clean or replace the components 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 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.
