Fuel gauge reading. Also, for USA models and maybe others, there is a pressure sensor in one, right side I believe. It is for the fuel evaporative purge system.

Dennis,

Nothing to do with trunk, have to jack the car & remove L/R covers, they are located at the bottom of the fuel tank..,,

little fun job...

ZAYED,,
daem bro, i thought it was a comfortable job from the trunk, removing plastic cover under carpet and voila fuel senders in front of me, my old volvo had the sender in trunk.

should you have an almost empty gastank when removing both senders?
would there be a gasleak if tank is full when senders are removed?

good to know thanks

Yes it should be bro.,

if you open the senders all fuel will fall-off completely,,

you can empty the tank, via the fuel pump hose, or air pumped/sucked via the cap, then return it again when new senders were installed...
