PROBLEM TO BE SOLVED: To provide a fuel supply system that can prevent unintended detachment of a liquid level detector from a mounting portion due to impact.SOLUTION: In a fuel supply system 1, a sender 3 includes: a base portion 19 inserted into a mounting hole 11; and a lock portion 20 provided at a tip of the base portion 19 and locking on a back surface 10b side of a sender mounting portion 10. The sender mounting portion 10 includes an unlocking restriction portion 21 that is arranged on the back surface 10b side separated from the mounting hole 11 and that opposes to the lock portion 20 in an unlocking direction for releasing the lock of the lock portion 20. In the unlocking direction, a first clearance a from one inner surface 11a to the other inner surface 11b of the mounting hole 11 is made larger than the width b of the lock portion 20, and a second clearance c from one inner surface 11a of the mounting hole 11 to the unlocking restriction portion 21 is made smaller than the width b of the lock portion 20.SELECTED DRAWING: Figure 2 【課題】衝撃によって意図せずして液面検出器が取付部から外れてしまうことを防止できる燃料供給装置の提供。【解決手段】燃料供給装置１において、ゼンダ３は、取付孔１１に挿入される基部１９と、基部１９の先端部に設けられてゼンダ取付部１０の背面１０ｂ側に係止する係止部２０と、を備え、ゼンダ取付部１０は、取付孔１１から離間した背面１０ｂ側に設けられると共に、係止部２０の係止を解除する係止解除方向で係止部２０と対向する係止解除規制部２１を備え、係止解除方向において、取付孔１１の一方の内面１１ａから他方の内面１１ｂまでの第１の離間距離ａは、係止部２０の幅ｂよりも大きく、且つ、取付孔１１の一方の内面１１ａから係止解除規制部２１までの第２の離間距離ｃは、係止部２０の幅ｂよりも小さい、という構成を採用する。【選択図】図２
