Thread: 39 Chevy Coupe - All Steel - having issue with gas tank

Tweet

Thanks....I poured a couple gallons but the meter reads as full tank. And they are closed end connectors. The tank is sitting level on floor. Ahhhhh...looks like I'm going to have to pick up an ohms meter to check this unit unless there's some other trick.

Ohms is the quickest check - take the wires loose and check between the black & a good chassis ground to see if it's zero'd. Then the same with the green, I think will show infinity. Also take a quick look at your fuel gauge, if you can see it easily, and check the connection color? Might not be a continuous wire, but worth a look. Remember your tank has to be grounded to the chassis for the gauge circuit to work - sitting on the floor you need to connect tank to chassis. That's the kind of thing I often forget, then scratch my head as to why I cannot get a signal....
