Where is the Fuel Sensor located?

Hello,

The fuel level sensor is part of the fuel sending unit. It is located in the fuel tank. It is the same unit that houses the fuel pump.
In order to replace the sensor, the fuel tank needs to be removed. That will provide access to the fuel sending unit.

Please let me know if you have any questions.
Thank you.
