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:

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