I'm trying to fill it, not to the very top, but the auto shut-off stops it at about two gallons short of full. The gauge almost reaches full, but drops quickly. When full, it stays on the full mark for quite awhile. It is supposed to hold about 22 gallons, but with about 2 gallons remaining in the tank, the pump shuts off between 17-18 gallons.
I have tried removing the nozzle after the first shut-off, letting the gas settle before adding more but it will still only take it at a very slow rate.
