REMOVAL
1. Inspect visible internal portion of fitting for dirt accumulation. Clean the fitting before disassembly.
NOTE: This fitting consists of a body, spacers. O-rings and a retaining clip. The clip locks the fitting on to the fuel or vapor tube depending on the application.
2. Some adhesion between the seals in the fittings and the tubes will occur with time. To separate, twist the fitting on the tube, then push and pull the fitting until it moves freely on the tube.
NOTE: If necessary, drain fuel tank.
3. Push disconnect tool into the connector to release internal locking fingers.
NOTE: Some fuel tubes have a secondary bead which aligns with the outer surface of the clip. These beads can make tool insertion difficult. To disengage the tube from the fitting, install Fuel Line Disconnect Tool 310-040 (T90T-9550-B) (5/16 inch) or 310-041 (T90T-9550-C) (3/8 inch) (Parts of 310-S039 (T90T-9550-S)) onto the fuel line or vapor tube to be disconnected.
4. Separate fuel tube or vapor tube from connector. Remove disconnect tool.
NOTE: Only moderate effort is required if the tube has been properly disengaged. Use hands only.
5. After disassembly, inspect and clean tube end sealing surface. Tube end should be free of scratches and corrosion as they result in paths for fuel or vapor leakage. Inspect the inside of the fitting for any internal parts such as O-rings and spacers that may have been dislodged from the fitting. Replace any damaged connector.
INSTALLATION
1. Install new connector/hose tube assembly if damage was found.
CAUTION: The steel push connect and spring lock couplings used on the flexible fuel vehicles have special O-rings for methanol fuel and ethanol fuel tube ends, steel compatibility.
2. Before installing fitting on tube, wipe tube end with a clean cloth. Inspect the inside of the fitting to ensure it is free of dirt and / or obstructions.
3. To install fitting onto the tube, align fitting and tube axially and push fitting onto tube end. When fitting is engaged, a definite click will be heard. Pull on fitting to ensure it is fully engaged. Applying a light coat of engine oil to the tube end will ease assembly.
