MPG chart.

My gas gauge broke (it swung so wildly that the needle finally broke off!). Since then I have been happy just looking at the reading from the fuel flow meter and then just adding back in what it says I used. I mentioned this to someone and they said that's fine as long as no one steals your gas. Obviously a flow meter won't pick that up like a level gauge would so you might get stuck out there. My boat is stored next to my house so that's unlikely but it did give me pause.

On a related note. Is it common to have the gauges swing with the sloshing in the tank or was mine somehow missing a damping device, circuit or function? I have seen some that are smooth and some that bounce around like mine did. If I can be assured that a new one would be smooth I would probably replace it.
