ABSTRACT:
The present invention is directed to a fuel supply system for a fuel burner of the type that requires for proper operation an excess flow of fuel to be provided to the burner with that excess being recirculated. The fuel system further requires that sufficient fuel is added to the system to make up for that amount of fuel which is fired or burned. The fuel supply system includes a fuel pump which selectively draws from a fuel supply the make-up fuel flow and from a return path the excess fuel flow for recirculation. At any given moment all fuel flow from one inlet line and the other inlet line is positively closed.
