Fuel Gauge is dead

Anyone ever replace the sending unit in a cc? My gauge doesn't work anymore and I believe the sending unit is bad. I've spoken to a mechanic and he said it isn't that hard to change out as long as the console isn't over the tank. Fortunatley, I've got an access right above the tank where I stand. I'm just not sure how hard it is to actually swap one out.

Depends on what type of sending unit you have...My original was a magnetic sender that was held on by two screws on the top of the tank...Removed the two screws, disconnected the wires, cleaned the area, put new sender on, connected the wires.......all done.. Others are mounted internally and have to be completely removed............
 
Make sure you check the wiring. The sending unit may be good but the wiring might be the problem.

How does your guage look? I just replaced my guage and sending unit as a set. I will be replacing all of my guages in the future so I replace the fuel guage at the same time as the sending unit.
 
If you touch the two wires together for the sending unit your guage should jump to full which is a quick test. The biggest thing to worry about when replacing the unit is not to crank down on the screws too much. Most tanks are aluminum and its easy to crank one to many turns and strip them out. I believe the last one I installed said to crank them down until you see the sealer around the screw to squeze out around the head of the screw.
 
Testing Sender

Touching the wires together and thereby avoiding the resistance created by the sender should send the gauge to full. On typical senders the full position is 33 ohms and empty is 240 ohms. Before you buy any parts I suggest you pull the sender and test it with a multimeter.

POST a pic of your sender so we can see what kind you have, Did you try jumping the wires yet, what results??
