Abstract:
To provide a manual fuel pump in which a load imposed on an environment is small compared with a fuel pump formed of polyurethane rubber, and which has fuel visibility.SOLUTION: A manual fuel pump 16 is constituted of a mixture including an elastic material which is lower than polyurethane in fuel permeability, and a filler for enhancing the transparency of the elastic material. Since the elastic material which is lower than the polyurethane in fuel permeability is used for the manual fuel pump 16, the load imposed on the environment is small. In addition to this, since the elastic material contains the filler for enhancing the transparency of the elastic material, it can be visually confirmed whether or not fuel is properly sucked at pumping.SELECTED DRAWING: Figure 1
