Fuel Level Sensor
The fuel gauge started reading irractically a few months ago, so I had to plan my fuel stops by relying on the tripodometer. I did some
research and found that the fuel level sensor was a common problem on these cars. There is an access hole in the trunk so you don't
have to lower the fuel tank, but the access hole is a bit on the small side, making the job tricky. And the easiest access is through the
fold down in the back seat, so you will be contorted during the job.
I bought the part from a local parts store and a few weeks later, did the install.....
Dorman #911-008.
Comes with new sensor, seal, float, wiring and retaining clips.
Start the car and remove the fuel pump relay. Turn the ignition off when the car stalls.
The next work will be done inside the car, and there will be gas fumes, so I lowered all the windows, removed the dome light fuse, and left all the doors wide open.
Pull back the carpet in the trunk to expose the access panel.
Remove the 7 10mm nuts and pry the panel off.
Once the pump was exposed, I got a scrub brush and poured some water over the pump to get rid of any loose debrit.
Disconnect the two plugs.
Disconnect the three fuel lines. For the two outer hoses, squeeze the two tabs inward
and pull the hose off. For the inner hose, squeeze the end inward and pull the hose off.
Remove the lock ring; rotate counter clockwise until it clears the 4 lock tabs.
Now to separate the lock ring and get the pump out. The access hole isn't quite big enough the pull everything straight out. I lifted everything up a bit, then managed
to remove the lock ring. It just barely clears the electrical plugs, so it is tricky to get off. Once off, pull the pump up and clear the float and the sock.
Remove the old sensor, wiring and seal.
New seal, sensor, float and wiring installed.
The lock ring.
Install is the reverse of the removal.
I got the pump back in the tank, but couldn't get the seal to seat properly. After many attempts, I decided to remove the pump and use the old seal. The old seal seated nicely allowing
the lock ring to be installed.
Everything back in place.
The gauge reading properly.
