Problems solved by technology
[0015] 3. It is arranged on the side below the concave portion 141 of the lower casing 14b of the fuel tank 14. This kind of existing fuel pump 143 installation structure can certainly shorten the filter element 1432 (that is, the oil suction port) of the fuel pump 143, and the fuel pump 143 The distance between the main body can reduce the load of the fuel pump 143 during operation, but because the fuel pump 143 is arranged in the recess 1 of the lower casing 14b of the fuel tank 14
[0016] 41, so when the fuel pump 143 is to be overhauled, the fuel pump 143 maintenance project becomes very difficult due to the limitation of the width of the recess 141

Embodiment Construction
[0071] In order to make it easier to understand the structure of the present invention and the effect that can be achieved, it is described as follows in conjunction with the drawings:
[0072] The motorcycle fuel pump arrangement structure of the present invention especially refers to a motorcycle fuel pump arrangement structure of a straddle injection engine. The structure will be described in detail, and the following will only be set forth for the fuel pump arrangement structure of the present invention.
[0073] First, see Figure 4 , 5 As shown, the motorcycle fuel pump installation structure of the present invention includes a base 2, a pressure regulating valve 3, a support arm 4, a fuel pump 5 and a fuel gauge 6.
[0074] The peripheral ring of the base 2 is provided with several coupling holes 21, and a gasket 27 is sheathed on the peripheral edge, and a fixing seat 22 is set on the base 2 in addition, and the fixing seat 22 is bent in an L shape, whereby one end i...
