Removal Procedure

WARNING:

Fuel Vapors can collect while servicing fuel system parts in enclosed areas such as a trunk. To reduce the risk of fire and increased exposure to vapors:

Use forced air ventilation such as a fan set outside of the trunk.
Plug or cap any fuel system openings in order to reduce fuel vapor formation.
Clean up any spilled fuel immediately.
Avoid sparks and any source of ignition.
Use signs to alert others in the work area that fuel system work is in process.
