That large fitting with the screws looks like a sending unit for measuring
how much water is in the tank. Its almost exactly like one I have on a
piece of equipment for measuring fuel. The screw in the middle would attach
to a wire which is then attached to the gauge. The fitting also looks
suspiciously like a fuel line port. In which case it would be attached to a
tube that draws from the bottom of the tank. Is it possible someone used a
(hopefully new) fuel tank as a water tank?
