• Q: How to replace the Fuel Level Sensor assembly on 2009 Cadillac DTS?

  A: The replacement process for the Fuel Level Sensor assembly starts with using ch 48027 to drain fuel system pressure or by performing the operation without the tool. First remove the rear compartment liner together with the Fuel Level Sensor access hole cover bolts before removing the cover. Remove connection of the fuel feed rear pipe quick connect fitting to its module and separate both Fuel Level Sensor wiring harness electrical connectors (1, 2) from the pressure sensor and module. Place the j 45722 (Fuel Level Sensor Lock Ring Wrench) on the lock ring while maintaining its safety to avoid damage. All procedures for dealing with the Fuel Level Sensor assembly should occur while keeping fingers clear of fuel pipes to protect them from damage. Handle the fuel module assembly carefully because it will rise while the reservoir bucket contains fuel that should be dumped into an approved receptacle. Operator j 45722 with a long breaker bar should unlock the fuel module lock ring which you must rotate counterclockwise. Raise the module vertically with great care to reveal the Fuel Level Sensor float arm while aiming it to pass through the tank opening. Before continuing discard the damaged o-ring present in the old fuel module and examine the lock ring for warping further than 0.41 mm (0.016 in), replace the lock ring if it fails to meet the measurement criteria. Before installation place a new fuel pump module o-ring seal onto the Fuel Tank with special attention to avoid bending the float arm. Use the j 45722 to create clockwise torque on the module lock ring until it reaches complete locking after installing it into the Fuel Level Sensor assembly. Reconnect both Fuel Level Sensor wiring harness electrical connectors (1, 2) along with the fuel feed rear pipe quick connect fitting to the module. The ignition should remain turned on for two seconds before being turned off for ten seconds followed by another ignition turn-on to identify any fuel leakage. Install the Fuel Level Sensor access hole cover before fastening its bolts with 2 nm (18 lb in torque) while placing back the rear compartment liner and fuel injector sight shield.
