I am not familiar with that particular fuel sending unit, but there should be some kind of connection as the fuel gage reads right off a rheostat controlled by the float in the tank. That is why some people have problems getting the right reading. They have a gage that uses one set of resistances and a pick up and unit that has another set of resistance. As the gas gets lower, the float goes down raising the resistance and thus lowering the reading of the gage. It has nothing to do with the fuel lines themselves. Unless this is a completely different kind of sending unit and pick up that I have no experience with at all.
