Gas guage sender unit

In the fuel tank...it's part of the pump and there is an access cover so you don't need to lower the tank. Why do you want to know? If the gauge is reading poorly these can usually be cleaned and tensioned rather than replaced. TG

Lift the carpet in the trunck area behind the driver's side rear seat, should be a big round access cover, remove the cover, the sending unit/fuel pump is on the round cover screwed on top of the tank. The screws holding the cover on the tank will probably be seized on, try turning them out and in until you get movement, apply a penetrating oil and keep working them slowly until they come off. Disconnect the wiring, the sender/pump come off with the cover. Try cleaning the contact area where the sender rubs with an eraser, this usually is the problem. Re-connect the wiring for the sender only, not the pump as it will be running dry, and move the float up and down and see if the gauge now works (stuff the open hole in the tank with rags BEFORE connecting any wiring).
