Tank on Empty

Erratic Fuel Gauge

We recently started driving a vanpool to work. Our fuel gauge is extremely non-linear. We have a 20 gallon tank. The gauge has been observed to jump a 1/4 level in less than 20 miles. It will stay on Full for about sixty miles and then jump down. The worst part is that it will stick on 1/4 full for a long time and then jump to near empty. The warning light came on with less than 1 gallon of fuel in the tank! Needless to say, now we just look at the miles travelled between fill-ups and use that as our gauge.
