Fuel Line

The fuel line (and EVAP canister purge line) is a multi-layer nylon tube covered with a protective, extruded sheath and molded to the correct routing configuration. The lines are mounted to the underbody and trunk with polymer clips and secured with plastic screws.

The fuel and EVAP lines are not repairable, and neither are their connector bodies. They must be serviced as a unit if they are leaking, damaged, kinked or crimped.

The connector quick connect retainers are not reusable and must be replaced after disconnecting connectors.

IMPORTANT:  The connector quick connect retainers are not interchangeable between 1.9L (L24/LL0), 2.2L (L61) or 3.0L (L81). When replacing retainers, ensure that the correct retainers are used.

The front fuel lines use a different type of fuel line connection at the fuel rail. To separate these lines, an expansion tool is required (J-37088-A).
