• Q: How to replace the Fuel Level Sensor on the left side on 2007 Chevrolet Corvette?

  A: The first step to replace the Fuel Level Sensor on the left side requires removing the module from the Fuel Tank by avoiding contact with the level sender on its resistor card to protect it from oil contamination. Position the 3 connector position assurance (CPA) lock tabs of the electrical connector and slide them downward to release the connector before removing the sender wires from their connector. To perform level sender replacement start by pushing the lock tab above the unit body then sliding the sensor out of its slot before removing it from the module while directing the wiring correctly into the back slot. Install the new level sender assembly into the slot until it reaches the lock tab engagement point. Connect the level sender wires to open slots of the electrical connector while ensuring proper wire placement next to the regulator ground wire. Afterwards, secure this connection to the flange. An ohmmeter should be used to check level sender resistance which must display 38.5-41.5 ohms in the empty stop position while displaying 247-253 ohms at the full stop position and showing no open circuits across the entire sweep range. Check the level sender resistance with a voltmeter across the empty tank position while it faces up so the module identifies an empty tank condition then flip the tank to verify the full stop reading. To verify the level sender operates freely within the tank an empty stop resistance check is done while the tank remains upright. Also validate that the level sender does not face any obstructions from interior factory system tubes.
