DISCONNECTING FUEL LINES
In order to install fuel system diagnostic equipment on vehicles equipped with plastic quick-connect fittings, fuel line separator tools must be used to
disconnect the fittings. Using the separator tools to release the fittings will cause the plastic retainer to remain inside the female connector allowing
diagnostic equipment to be connected.
TOOLS REQUIRED
J37088-A tool set, fuel line quick-connect separator
J39504 tool set, fuel line quick-connect separator (restricted access).
REMOVE OR DISCONNECT
1. Relieve fuel system pressure. Refer to Fuel System Pressure Relief Procedure.
2. If equipped, slide dust cover back to access quick-connect fitting.
3. Grasp both sides of fitting. Twist female connector 1/4 turn in each direction to loosen any dirt within fitting.
WARNING: Safety glasses must be worn when using compressed air, as flying dirt particles may cause eye injury.
4. Using compressed air, blow dirt out of fitting.
5. Choose correct tool from J37088-A or J39504 tool set for size of fitting. Insert tool into female connector, then push/pull inward to release
locking tabs.
6. Pull connection apart.
CLEAN AND INSPECT
NOTE: If it is necessary to remove rust or burrs from fuel pipe, use emery cloth in a radial motion with the pipe end to prevent damage to 0-ring
sealing surface.
