Abstract
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.
