You didn't specify which bike you're riding, but if the fuel tank sender only has one wire it probably uses the tank to complete the circuit. This used to be common on older cars, and I assume also on vintage bikes.

Modern bikes use two wire senders where there's a ground connection in the wiring loom. I'd imagine that modern cars have already started using digital sensors which communicate over CAN bus, but hopefully it'll be a while before this arrives on bikes.

So, if your sender only has one wire you might need to remove paint residue to ensure a decent connection, but on most bikes there's no need.
