PROBLEM TO BE SOLVED: To prevent any harmful effect generated by flowing-down of surplus fuel from a regulator into fuel stored in a fuel storing tank, to enable fuel not mixed with any impurities to be stably supplied to an engine.SOLUTION: Leg segments 91, 92 that can be installed at supporting plates 123, 124 protruded and arranged at a fuel storing tank 12 are protruded and arranged at lower surfaces at both ends, a receiving surface 95 for mounting a holding flange 44 of a regulator 4 at a part of the surface in a holding member main body 94 having a length where one end part 93 approaches an inner wall surface 121 is formed at the upper end surface, surplus fuel from the regulator 4 can be transferred back along the inner wall surface 121 of the fuel storing tank 12 through a surplus fuel discharging passage 97 by a holding member 9 of the regulator having a regulator receiving part 96 formed with a trough-like surplus fuel discharging passage 97 held while having a space between it and a return port 43 of the regulator 4 and communicated over the end part 93.SELECTED DRAWING: Figure 2 |
