ABSTRACT:
An arrangement for mounting a fuel metering control pump on an internal combustion engine comprises the air intake system via which air is drawn into the engine, said system including a generally annular support element on which the control pump mounts. Means are provided for mounting the annular support element on the intake manifold of the engine with induction air passing through a central aperture defined by the inner periphery of the annular support element. The control pump is disposed adjacent this aperture and meters fuel via a suitable fuel distribution system into the induction air stream to form the combustible mixture for the engine. The control pump includes an inlet port which passes through an opening in the wall of the annular support element to provide for connection of a fuel supply line thereto exteriorly of the air intake system. A similar arrangement is provided for a return line to the fuel tank. The annular support element is further provided with an upstanding flange around its outer periphery on which an annular element is supported. The usual annular air filter element is supported on this latter annular element and a cover encloses the entire assembly.
