Default Got a twitch.

Anybody ever have their fuel gauge go all "twitchy"?
Cant afford to fill it up, cant afford to run it empty!

Sounds like a bad wiring connection or a bad float sending unit. The FAQ has a write up on swapping in a new float.

Would a bad float sending unit cause the gas gauge to only act up during certain spots in the tank? For example, from 3/4's of a tank to 1/2 a tank, my gauge will go all over the map, but above 3/4's, or under 1/2, the gauge works fine..

Yes if there is a bad spot on the resister board, which is common since it can rub off over time.
