My lift doesn't have a water pump and my current reg isn't ported for water. It is hanging by wire against the exhaust manifold (I believe because the former owner had freezing problems). This baby is a sweet rig! Parts vender - ha, I'm one my own here. Found a new finned G-85 online for $100, I think I'm going to try it unless someone here tells me different. The one I have has some wires on it near the "prime button". The new one does not.
