Abstract
An outboard motor auxiliary fuel tank/fuel pump assembly includes an auxiliary fuel tank disposed in an engine compartment and a fuel pump joined to one side of the auxiliary fuel tank for supplying fuel stored within the auxiliary fuel tank to fuel injection valves of an engine. A float of a float valve provided within the auxiliary fuel tank is supported in the auxiliary fuel tank via a pivot shaft that is parallel to a tilt shaft of an outboard motor. First and second mounting bosses on which the fuel pump can be mounted are formed on the right side face and the front end face of the auxiliary fuel tank.
Claims2
