fuel sender unit location and heater wont work blowing fuse

Hello,

The fuel level sensor is located on the fuel pump assembly in the fuel tank.
In order to replace that part, you will have to access the fuel pump.
On this vehicle there is an access port in the trunk above the fuel pump. Remove the carpet lining in the trunk and that will uncover the access port.
Simply remove cover to have access to the pump.

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