ABSTRACT:
A combination draw valve and sending unit assembly includes a draw valve assembly and sending unit assembly. The draw valve assembly is constructed for drawing fuel from a fuel tank of a truck or other motor vehicle. The draw valve assembly includes an adapter valve and a float valve constructed for automatically closing so that no fuel can be withdrawn from the fuel tank when the fuel level in the tank is low. The sending unit assembly inlcudes a potentiometer and a magnetic contact wherein the magnetic contact is coupled to the float valve for providing an electrical signal indicative of the amount of fuel remaining in the fuel tank.
