Such a conventional fuel extraction device for the fuel tank 1 has many drawbacks as follows.The first is that when operating the fuel pot 5, the screwing part between the fuel pot 5 and the fuel tank 1 is difficult to operate. There is a risk that unnecessary bending and twisting forces will act on the screws, causing loosening of the threaded portions 4 and 13, resulting in fuel leakage. Secondly, in such a structure, in order to increase the area of the filter 10,
Although it is necessary to change the entire structure of the fuel tank 5, it is impossible to do so by simple modification. Therefore, the filter 10 often gets clogged, making maintenance difficult. Thirdly, when vapor lock occurs on the carburetor side (not shown) of the fuel stock, it is necessary to release the bubbles in the reverse order of the fuel flow described above. Since the fuel reservoir has a V-shape at 9 portions, it is extremely difficult to release air bubbles. Fourthly, because the fuel pot 5 is directly screwed into the fuel tank 1, the fuel pot 5
The degree of freedom in arranging is limited.
