ABSTRACT:
Disclosed is an engine fuel flow restriction warning system comprising an engine including a first conduit means connecting a fuel storage means and a fuel pumping means. A second conduit means connects a fuel pumping means with an engine fuel inlet means. Pressure sensing means communicates with the first conduit means, and the pressure sensing means operates a warning means to produce a warning when the pressure in the first conduit means reaches a predetermined low level. When used with an engine including a cooling system and a cooling system temperature sensing means communicating with the engine cooling system, the temperature sensing means operates the same pressure warning means to produce a warning when the temperature in the engine cooling system reaches a predetermined level.
