A unitary temperature control bypass and fuel filtering device for an engine for heating fuel in the fuel filter. The device has an entry passage for receiving excess fuel from the engine, a first outlet passage for communicating with the fuel tank and a second outlet passage directing heated fuel into the fuel filtering device and then terminating in the first outlet passage. A central chamber communicating with the entry and outlet passages is centrally located between the passages and has a piston therein having reciprocal movement between the outlet passages for selectively blocking one of the outlet passages, wherein the piston is responsive to the fuel temperature in the filtering device.

[ What is claimed is:] [1.] A fuel temperature control bypass system for an engine having an inlet port for receiving fuel and an outlet port for returning excess fuel from the engine, said system comprising:a fuel tank for containing a supply of fuel;means for communicating fuel from the fuel tank

[ What is claimed is:] [1.] A fuel temperature control bypass system for an engine having an inlet port for receiving fuel and an outlet port for returning excess fuel from the engine, said system comprising:a fuel tank for containing a supply of fuel;means for communicating fuel from the fuel tank to the inlet port of the engine;a fuel filter disposed between the fuel tank and engine for receiving the fuel therein from the fuel tank and filtering said fuel before said fuel enters the inlet port of the engine;means for communicating the excess fuel from the outlet port of the engine to the fuel tank;means for sensing the temperature of the fuel in the fuel filter; andmeans for diverting all the excess fuel to flow adjacent the fuel filter, when the temperature of the fuel in the fuel filter is less than a specified temperature.
