To provide a fuel supply device for an outboard engine, which can stably and highly accurately supply fuel by making it possible to suppress occurrence of harmful effects due to downward flow of surplus fuel.SOLUTION: A fuel supply device 1A for an outboard engine includes, in a housing 2, a fuel pump 3 and a regulator 4 that adjusts fuel to a predetermined pressure and returns surplus fuel to a fuel storage tank 2a, and supplies the fuel of the predetermined pressure to an engine. On an upper side in the inside of the housing 2, a regulator holder 40 is arranged, which forms a surplus fuel discharge path 28 for sending the surplus fuel to the fuel storage tank 2a in a state that a lower part of the regulator 4 is inserted and supported. The regulator holder 40 has a funnel-shaped structure in which a tubular foot portion 40b is disposed extending downward from a bottom surface of a cup-shaped support portion 40a that supports the regulator 4 from below, and a tip of the foot portion 40b is located below an oil level of the fuel stored in the fuel storage tank 2a.SELECTED DRAWING: Figure 2
【課題】船外機用エンジンの燃料供給装置について余剰燃料の流下に伴う弊害の発生を抑制可能として燃料を安定的かつ高精度に供給できるようにする。【解決手段】ハウジング2内に燃料ポンプ3と燃料を所定圧力に調整して余剰燃料を燃料貯留槽2aに戻すレギュレータ4を備えて所定圧力の燃料をエンジンに供給する船外機用燃料供給装置1Aであって、ハウジング2内部の上部側に、レギュレータ4の下部を挿入・支持した状態で余剰燃料を燃料貯留槽2aに送る余剰燃料排路28を形成するレギュレータホルダ40が配設され、そのレギュレータホルダ40がレギュレータ4を下から支えるカップ状の支持部40の底面から管状の足部40bが下向きに延設された漏斗状の構造を備えて、その足部40bの先端が燃料貯留槽2aに貯留した燃料の油面下に位置するものとした。【選択図】図2
