A fuel supply apparatus particularly for the outboard motor is capable of decreasing the need to change the layout, etc., according to the specification of an engine to reduce the cost of production by preventing vapor from being discharged into an intake pipe. A low pressure fuel pump has its discharge flow rate adjusted to be greater than that of a high pressure fuel pump, and surplus fuel accumulating in a volumetric chamber is caused to circulate through the volumetric chamber, a first return passage, fuel piping, and an inflow passage under the acti...
What is claimed is: 1. A fuel supply apparatus comprising: a volumetric chamber that is arranged in a casing of an outboard motor; a low pressure fuel pump that is connected to a fuel tank arranged outside of said casing through fuel piping, and at the same time to said volumetric chamber through an inflow passage so as to supply fuel from said fuel tank to said volumetric chamber; a first one-way valve that is arranged in said inflow passage so as to allow fuel to flow from said low pressure fuel pump to said volumetric chamber; a first return passage ...
