J 37088-A Tool Set, Fuel Pipe Quick-Connect Separator

Caution: In order to Reduce the Risk of Fire and Personal Injury:

   • If nylon fuel pipes are nicked, scratched or damaged during installation, Do Not attempt to repair the sections of the nylon fuel pipes. Replace them.
   • When installing new fuel pipes, Do Not hammer directly on the fuel harness body clips as it may damage the nylon pipes resulting in a possible fuel leak.
   • Always cover nylon vapor pipes with a wet towel before using a torch near them. Also, never expose the vehicle to temperatures higher than 115°C (239°F) for more than one hour, or more than 90°C (194°F) for any extended period.
   • 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.)

Notice: Do not attempt to straighten any kinked nylon fuel lines. Replace any kinked nylon fuel feed or return pipes in order to prevent damage to the vehicle.

Notice: Replace the EVAP pipes and hoses with the original equipment or parts that meet the GM specifications for those parts. The replacement EVAP pipe must have the same type of fittings as the original pipe in order to ensure the integrity of the connection. When replacing EVAP hoses, use only reinforced fuel-resistant hose identified with the word Fluoroelastomer or GM 6163-M on the hose. The inside hose diameter must match the outside pipe diameter. Do not use rubber hose within 100 mm (4 in) of any part of the exhaust system or within 254 mm (10 in) of the catalytic converter.

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.

Installation Procedure

Caution: In order to Reduce the Risk of Fire and Personal Injury: If nylon fuel pipes are nicked, scratched or damaged during installation, they must be replaced.

Notice: Always re-attach the fuel lines and fuel filter with all original type fasteners and hardware.

Do not repair sections of fuel pipes.

Important: If fuel line bundle attaching hardware is damaged or broken replace it.


    Object Number: 32189 Size: SH
  1. Install the new fuel feed, fuel return, and EVAP pipes and the fuel and EVAP pipe attaching hardware as noted during removal.
  2. Remove the caps from the in-pipe fuel filter pipe, the fuel feed pipe, and the fuel return pipe.
  3. Install the fuel return pipe quick-connect fitting in front of the fuel tank. Refer to Metal Collar Quick Connect Fitting Service .

    4. 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.

  4. Install the fuel feed pipe threaded fitting at the outlet of the in pipe fuel filter.

    5. Tighten
    Tighten the in-pipe fuel filter fitting to 30 N·m (22 lb ft).

  5. Lower the vehicle.

  6. Install the fuel feed (1), and fuel return pipe (2) quick-connect fittings in the engine compartment. Refer to Metal Collar Quick Connect Fitting Service .
  7. Add fuel and install the fuel tank filler pipe cap.
  8. Tighten the fuel tank filler pipe cap.
  9. Install the negative battery cable.
  10. Inspect for leaks.
    11. 10.1. Turn the ignition switch to the ON position for 2 seconds.
    10.2. Turn the ignition switch to the OFF position for 10 seconds.
    10.3. Turn the ignition switch to the ON position again.
    10.4. Visually inspect the fuel system for fuel leaks.
