Fuel recirculation methods, fuel supply circuits and fuel recirculation valves for selectively mixing hot return fuel from a diesel engine with fuel from a tank before providing it to back to the engine. In exemplary disclosed embodiments of fuel recirculation valves, the valves are configured to selectively mix the fuel in a controlled manner using a temperature sensitive actuator within the valve such that, when the temperature of the fuel reaches a certain point, the valve restricts flow pathways to reduce heated fuel being mixed with fuel from the fuel tank, and eventually closes to prevent any heated fuel from being mixed and overheating the fuel provided to a fuel filter, a fuel pump and the engine. Disclosed fuel circulation valves are separate from the fuel filter and are placed upstream of the filter.
