Fuel supply unit for vehicle

摘要

The invention promotes separation of returned fuel into liquid fuel and gases. A base plate 34 of a fuel pump assembly 33 is attached, from the lower side, to a rear part of a bottom 30 of a fuel tank 1. A fuel pump 1 and a strainer 4 communicating with an inlet port 3 are housed in the fuel tank 1. A small partition 36 made of an elastic material such as rubber covers the front, right and left sides of the strainer 4, and partially supports a fuel-adsorbing member 35 arranged on the strainer 4. The fuel-adsorbing member 36 is a spongy filter made of stainless steel coils and having a great number of minute pores, adsorbs the fuel returned via a fuel return pipe 10, and separates the fuel into gases and liquid fuel. The liquid fuel remains adsorbed onto the fuel-adsorbing member 35 and stays near the strainer 4.
