Fuel gauge limiter

I've had several vehicles where the 2 nut/bolts holding the guage to the circuit board were corroded.. I disconnected battery, and got in behind with a small wrench,, and worked the two nuts back and forth,, then snugged em down,, solved the prob..

As mentioned,, it's a slow intermittant pulse of electricity to the tank..

Also mentioned is that little metal ground strap bridging the rubber hose at the tank, that's the ground..
