An apparatus is described for enabling an engine to burn either liquid fuel or gaseous fuel, which apparatus comprises: (i) a gaseous fuel control valve for installation in a gaseous fuel supply line leading from a gaseous fuel storage container to an intake manifold of the engine, (ii) a liquid fuel shut-off valve for shutting off the supply of liquid fuel when the engine is to run on gaseous fuel, and (iii) a gaseous fuel shut-off valve for shutting off the supply of gaseous fuel when the engine is to run on liquid fuel, the gaseous fuel control valve comprising: (a) housing means defining a compartment, (b) a diaphragm which is positioned in the compartment and which defines one wall of a chamber, the housing means defining the remaining boundaries of the chamber, and the side of the diaphragm opposite the chamber being in communication with atmospheric pressure, (c) a gas inlet into the chamber and adapted for connection with a conduit leading from the gaseous fuel storage container, (d) a gas outlet from the chamber and adapted for connection to an intake manifold of the engine, (e) outlet valve obturator means which is controlled by an accelerator pedal of a vehicle in use of the apparatus and which is for controlling the intensity of the suction applied to the chamber in response to the position of the accelerator pedal, (f) inlet valve obturator means for controlling the flow of gaseous fuel through the gas inlet into the chamber.
