Fuel Level Sensor: Service and Repair
Removal Procedure
Caution: Gasoline or gasoline vapors are highly flammable. A fire could occur if an ignition source is present. Never drain or store gasoline or
diesel fuel in an open container, due to the possibility of fire or explosion. Have a dry chemical (Class S) fire extinguisher nearby.
Caution: Provide proper ventilation when working with fuel in enclosed areas where fuel vapors can collect. The lack of adequate ventilation
may result in personal injury.
Caution: Always wear safety goggles when working with fuel in order to protect the eyes from fuel splash.
Caution: Remove the rear compartment floor trim to provide technician contact with the vehicle's metal surfaces. Failure to remove the rear
compartment floor trim may cause a static electricity discharge to ignite any fuel vapor resulting in personal injury and vehicle damage.
Caution: Fuel Vapors can collect while servicing fuel system pads 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.
Notice: Cap the fittings and plug the holes when servicing the fuel system in order to prevent dirt and other contaminants from entering the open pipes
and passages.
Notice: Clean all of the following areas before performing any disconnections in order to avoid possible contamination in the system:
^
The fuel pipe connections

The hose connections
^
The areas surrounding the connections
