acardon,Some replacement tanks had a drain plug in the bottom but the originals didn't. Siphom hose.
i will be under it this next weekend as soon as i can clear/clean a path the drain would be nice...maybe you know what i mean.Aero does it have a drain plug in the bottom of the tank? My original tank had a drain plug and the new tank did too. Mine isn`t a wagon though.
