Abstract
A pulsation preventive member for use with a pump constructed in the form of a hose disposed in a pump fluid passage. The hose is located in a fuel tank in such a manner that one end of the hose is connected with the pump and the other end of the hose is connected with a injector or the like. The hose is constructed so as to substantially inhibit pulsation by elastically deforming. The hose may have a substantially circular cross-sectional shape and a mesh-shaped thread layer incorporated therein. The mesh angle of the thread layer is preferably less than 50 degrees. Alternatively, the hose may have non-circular cross-sectional shape such as rectangular or elliptical cross-sectional shape. Further, the hose may be constructed so as to have a double-walled structure comprising an inner layer and an outer layer in the form of a hose with a plurality of connecting members interposed therebetween.
