Fuel Line Coupler: Service and Repair

QUICK CONNECT COUPLING

Disconnect - Type I

WARNING:
- Do not carry lighted tobacco or open flame of any type when working on or near any fuel-related components. Highly flammable vapors are always present and can ignite. Failure to follow these instructions may result in personal injury.
- Do not carry personal electronic devices such as cell phones, pagers or audio equipment of any type when working on or near any fuel-related components. Highly flammable mixtures are always present and may be ignited. Failure to follow these instructions can result in personal injury.
- This procedure involves fuel handling. Be prepared for fuel spillage at all times and always observe fuel handling precautions. Failure to follow these instructions may result in personal injury.

CAUTION:
- If the liquid or vapor tube is damaged (torn, holes or delaminated), the affected tube assembly must be replaced with a new tube assembly. Do not use aftermarket sleeving. Do not re-adhere loose sleeving material.
- When reusing liquid or vapor tube connectors, make sure to use compressed air to remove any foreign material from the connector retaining clip area before separating from the tube. Apply clean engine oil to the end of the tube before inserting the tube into the connector.
- Fuel injection equipment is manufactured to very precise tolerances and fine clearances. It is therefore essential that absolute cleanliness is observed when working with these components. Always install blanking plugs to any open orifices or tubes.

1. Release the fuel system pressure.
2. Disconnect the battery ground cable.







3. Disconnect the fuel tube quick connect coupling.
- Press the fuel tube quick connect coupling button and pull the fuel tube to disconnect.
