Zusammenfassung:PROBLEM TO BE SOLVED: To manufacture at low cost a fuel supply device having an external pump and a fuel supply device having no external pump by using a housing in which the same high-pressure pump used according to application is mounted.SOLUTION: A fuel supply device can supply fuel, stored in a fuel storage tank 12 formed in a housing 11, so as to cope with sudden acceleration or sudden deceleration of an engine by arranging a high-pressure pump 3 in the housing 11. To the fuel supply device, a first connector 4 having a low-pressure pump 41 having a fuel supply pipe connection port from a fuel tank, and a second connector 5 having no pump can be selectively attached through the same connector attachment part formed on the side wall of the housing body 11. 【課題】用途に応じて使用する同一の高圧ポンプを内蔵したハウジングを用いて外付けのポンプを用いる燃料供給装置とポンプを用いない燃料供給装置とを廉価に製造することを可能にする。【解決手段】ハウジング11内に高圧のポンプ3を配置してハウジング11内に形成した燃料貯留槽12に貯留させた燃料をエンジンの急加速や急減速にも対応して供給可能とした燃料供給装置を、燃料タンクからの燃料供給パイプ接続口を有する低圧ポンプ41を有する第1のコネクタ4およびポンプを有していない第2のコネクタ5の2種類のコネクタをハウジング本体11の側壁に形成した同一のコネクタ取付部を介して選択的に取り付け可能とした。【選択図】図2
