Default Fuel tank sender part number

2002 Subaru WRX sedan 5sp manual Turbo

Build date (june 2001)


My fuel gauge under reads when close to empty (the left side sender is most likely faulty. It reads 'E' with 3 gallon in the tank




Will the 42081SA020 part fit on this car.



Someone nearby for sale. Not close enough to drive there and check part against old part

passenger side sender (the one with the fuel pump, etc.) is part number 42081FE021 (supersedes 42081FE020)

The part number you found will definitely fit your car, but it's for the drivers side of the tank.

Thank you for responding. I did correct the first post.

I am looking for non the fuel pump side sender.

I assume this sender is responsible for the reading when fuel is < 50% in the tank

opposed forces and the dealer say this is not for my car.

I won't look up parts for you but I can help you diagnose the fault. The Sub sensor (driver side) and Main sensor (passenger side w/pump) are wired in series.
Sub sensor resistance - 0.5 to 2.5 ohms (FULL) and 50 to 52 ohms (EMPTY)
Main sensor - resistance 0.5 to 2.5 ohms (FULL) and 42 to 44 ohms (EMPTY)
