ABSTRACT A safety device for controlling the flow of fuel to internal combustion engines so as to protect an engine against damage due to insuffient oil pressure in the lubricating system. The device has a main body with a main fuel passageway therein and a main valve in the main fuel passageway controlling the normal flow of fuel between an inlet port and an outlet port, the main valve closing when a lubricant pressure sensor indicates that the pressure in the engine's lubricating system is below a predetermined value. The device has a bypass fuel passageway operable to allow a predetermined restricted amount of fuel to flow from the fuel inlet port to the fuel outlet port, and having a normally closed bypass valve blocking the bypass fuel passageway. The bypass valve actuator is located remote from the body of the main fuel passageway and includes a manually-operable pushbutton with means for locking the pushbutton in a position corresponding to the bypass valve being opened. The device provides a remotely actuated non-electrical, simple and reliable override function for a fuel cut off arrangement.
