Fuel Sender Assembly: Removal
WARNING: This page is about a different car, the 2003 Cadillac Seville and 2003 Cadillac DeVille. However, it is still accessible from the selected car via links, so may be relevant.
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.
CAUTION:
In order to prevent damage, cover the fuel pipe fittings with a shop towel before disconnecting the fuel pipes or removal of the fuel sender retaining ring, in order to catch any fuel that may leak out. Place the towel in an approved container when procedure is completed. DO NOT handle the fuel sender assembly by the fuel pipes. The amount of leverage generated by handling the fuel pipes could damage the joints.
NOTE:
It is not necessary to remove the fuel tank to access the fuel sender assembly. Vehicles are equipped with a fuel sender assembly access panel located in the rear compartment (trunk).
- Release fuel system pressure. See FUEL SYSTEM PRESSURE RELEASE . Drain the fuel tank. See FUEL TANK DRAINING .
- Remove the fuel sender access panel. See FUEL SENDER ACCESS PANEL . Disconnect the fuel sender quick-connect fittings. See FUEL LINE DISCONNECT FITTINGS . Disconnect the fuel sender assembly electrical connector.
- Disconnect the fuel tank pressure sensor electrical connector. See Figure. Remove the fuel sender retaining ring using the fuel sender lock nut wrench. The fuel sender assembly will spring-up when the locking ring is removed.
- When removing the fuel sender assembly from the fuel tank, the reservoir bucket on the fuel sender is full of fuel. The fuel sender must be tipped slightly during removal in order to avoid damage to the float. Place any remaining fuel into an approved container once the fuel sender is removed from the fuel tank. Remove the fuel sender assembly. Clean the fuel sender sealing surfaces. Inspect the fuel sender sealing surfaces.
