Servicing Quick Connect Fittings Plastic Retainers
Removal Procedure
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: Wear safety glasses when using compressed air in order to prevent eye injury.

- Blow any dirt out of the quick connect fitting, using compressed air.
- Squeeze the retainer tabs. Refer to Servicing Quick Connect Fittings (Plastic Collar).

- Remove the retainer.
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.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.
- Apply a few drops of clean engine oil to the male fuel pipe end.

- Push both sides of the quick-connect fitting together in order to cause the retaining tabs/fingers to snap into place.
- Once installed, pull on both sides of the quick-connect fitting in order to make sure the connection is secure.
