Leak Repairs

Each component joint in the fuel system is a potential leak path. For further information regarding the installation of hoses and seals, refer to the relevant service information.

The fuel filler cap is the only component that is frequently disturbed and as such is the most likely leak path. When installing the fuel filler cap, it should be tightened securely (until 3 clicks are heard) to guarantee a leak free system.

The diagnostic module tank leakage pump is not sealed internally at the electrical connector. The wiring harness connector contains grommets and a conventional seal. This connector must be installed securely to guarantee a leak free system.
