1. With the vehicle in NEUTRAL, position on a hoist.
2. WARNING:
- The evaporative emissions system contains fuel vapor and condensed fuel vapor. Although not present in large quantities, it still presents the danger of explosion or fire. Disconnect the battery ground cable from the battery to minimize the possibility of an electrical spark occurring, possibly causing a fire or explosion if fuel vapor or liquid fuel are present in the area. Failure to follow these instructions can result in personal injury.
- Do not smoke or carry lighted tobacco or open flame of any type when working on or near any fuel related component. Highly flammable mixtures are always present and may be ignited. Failure to follow these instructions may result in personal injury.
Disconnect the battery ground cable.

1. CAUTION:
- 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.
- 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.
NOTE: If the fuel tube retainer clip is broken or damaged, install a new clip using a suitable fuel line disconnect tool to separate the retaining clip legs. Once the retainer legs have been separated, lift the clip out of the connector housing, lifting from the stamped side of the connector body.
Disconnect the quick-connect fitting.
- Push the connect toward the tube to release the pressure.
