Using the info on audiworld I removed the rear seats of my car today and got out my multimeter...unfortunately I couldn't get any readings from it (user error).

Anyway, with both sensors unhooked I had no readings from the fuel guage. With the right (passenger) side hooked up but the left (driver) side unhooked I had no readings. When I hooked up the left side the gas guage jumped up.

Would this indicate the passenger side sensor is bad or do I need to figure out the multimeter to be sure?

Also...where is the best place to purchase sensors? Neither ECS or BP carry the sensors.

Thanks.
