A manually operated fuel valve having OFF, ON and RESERVE positions which comprises a valve body with a standpipe extending therefrom for receiving fuel from a fuel tank and supplying fuel to an engine the said valve is in an ON position. the valve body defines a first passage therethrough in communication with the standpipe for permitting passage of fuel to a fuel exit port when the valve is in the ON position. The valve body defines a second passage therethough for fuel to said exit port when the valve is in a RESERVE position. A rotatable fuel regulator member is positioned in the valve body for blocking the second passage when the regulator member is in a valve ON position and permitting passage of fuel through the standpipe and the first passage. The regulator member is effective to block passage of fuel from passing through both of the passages when rotated to an OFF position. The regulator has a third position intermediate the ON and OFF positions for permitting passage of fuel from the tank to the exit port through the second passage when the level of fuel in the tank falls below the top of the standpipe, and means are coupled to the regulator member for rotation therewith and arranged to provide a positive indication when said regulator is in the third position.
