ABSTRACT:
A liquid propane gas fuel system includes a propane fuel tank. A two stage pressure regulator defined by a housing with a fuel inlet and a fuel outlet is also included. A first fuel conduit extends from an outlet in the fuel tank to the fuel inlet in the pressure regulator. The system supplies fuel to an engine that includes an exhaust gas manifold. A thermoconductive mounting bracket is secured to the housing of the pressure regulator and manifold to transmit heat from the manifold to the regulator in proportion to the load imposed on the engine. A chokeless carburetor is also included in the system and is in fluid communication through a second fuel conduit with the outlet of the pressure regulator. In an alternative embodiment, a heat exchanger is included in the first fuel conduit. In a second alternative embodiment, an electric heating element is positioned within the housing of the pressure regulator.
