Q: How to replace the fuel level sensor on Chevrolet Colorado?
A: Start by sanitizing the fuel pipe attachments and hose fittings and nearby regions before commencing the Fuel Level Sensor replacement operation. The first step requires removing the Fuel Tank before disconnecting the evaporative emission (EVAP) line quick connect fittings between the module and vent valve. Besides this disconnecting step comes removal of the evap line from the Fuel Tank side clip and disassembly of its retention features. To begin remove the fuel feed line quick connect fitting from the module then remove it from its retaining feature which is molded into the Fuel Tank. The j 45722 (Fuel Sender Lock Ring Tool) needs installation onto the Fuel Pump module lock ring while also protecting the lock ring from damage and maintaining both hands away from the fuel pipes. The technician should use the j 45722 tool and breaker-bar to rotate the lock ring counterclockwise until it unlocks before removing the tool to raise the module from the tank. Tipping the module will allow clearance for the sensor arm and float. Remove and throw away the old Fuel Pump module seal before draining the fuel into an authorized container. Checking the sealing surface of the Fuel Pump module remains a necessary step before examining the lock ring for any signs of damage or estimating warpage beyond 0.41 mm (0.016 in). If such warpage is detected, a new lock ring needs to be installed. Installation requires cleaning the male port on the Fuel Pump module while applying new Fuel Tank module seal on the Fuel Tank before inserting the module making sure the sensor arm and float do not obstruct the opening. Begin by placing the module in position and setting the tang to fit the notch of the Fuel Tank before installing the lock ring. With the j 45722 turn the lock ring clockwise and fasten it before joining the fuel feed line quick connect to the module tank retention feature. The evap line quick connect fittings must be applied to the module and vent valve while fitting into the tank retaining features before placing them onto the Fuel Tank clip on the side wall.
Q: How to replace the Fuel Level Sensor assembly on Chevrolet Malibu?
A: The j 45722 Fuel Level Sensor lock ring wrench alone should be used for disconnecting evap and fuel feed lines from the Fuel Level Sensor assembly to prevent damage to the lock ring. Secure the Fuel Tank to prevent rotation because only significant force will release the lock ring while handling of the Fuel Level Sensor assembly by fuel pipes must be avoided to maintain joint integrity. Apply the j 45722 to the Fuel Level Sensor lock ring followed by a long breaker-bar while rotating counterclockwise to unlock it then remove the Fuel Level Sensor assembly together with the seal and discard the seal. Wash the Fuel Level Sensor sealing areas while checking the lock ring for damage; change the lock ring if it shows warping greater than 0.41 mm (0.016 in). A new seal must be used for the Fuel Level Sensor assembly installation while the Fuel Pump Strainer remains horizontal and the float arm stays obstruction-free. Fit the Fuel Level Sensor assembly with the lock ring while utilizing the j 45722 tool to guide correct installation of clockwise rotation. The final step involves attaching the fuel feed along with evap lines to the sensor assembly then reinstalling the Fuel Tank.
Q: How to replace the fuel level sensor on Chevrolet Tahoe?
A: The fuel level sensor replacement starts with unmounting the fuel sending unit. Start the replacement of the fuel level sensor by disengaging the electrical connector through retainer engagement before you take off the fuel level sensor electrical connector. Start by moving the locking tangs towards the inside of the sending unit bucket before extracting the fuel level sensor out from the bucket. The new fuel level sensor installation requires sliding the part down through the sending unit bucket with active locking tang engagement. Insert the fuel level sensor electrical connector into position before checking that the retainer does not have any gaps. Complete installation by putting in the fuel sending unit.
