Abstract

Provided is a fuel supply system. The fuel supply system includes a fuel pump module mounted in a fuel tank and including a reservoir having a predetermined amount of fuel filled therein and a fuel pump mounted in the reservoir to suck the fuel filled in the reservoir and supply it to an internal combustion engine; a fuel supply line supplying fuel from the fuel pump module to the internal combustion engine; and a fuel return line returning the fuel from the internal combustion engine to the fuel tank, wherein the inside of the reservoir is provided with a bypass tube connecting the fuel return line to the fuel pump to directly supply the fuel returned through the fuel return line to the fuel pump through the bypass tube.

Description

[0001] Related Application Cross Reference [0002] This application claims priority under 35 U.S.C. Section 119 to Korean Patent Application No. 10-2010-0003768 filed in the Korean Intellectual Property Office on January 15, 2010, the disclosure of which is incorporated herein by reference. technical field [0003] The present invention relates to a fuel supply system capable of supplying fuel to an internal combustion engine and returning fuel from the internal combustion engine to a fuel tank, and more particularly the present invention relates to a fuel supply system capable of feeding fuel through The fuel from which impurities are removed by various filters is used in the internal combustion engine, and the remaining fuel is directly supplied to the fuel filter, thereby supplying cleaner fuel to the internal combustion engine, and using the returned fuel as a working fluid during fuel supply to increase the fuel pump durability. Background technique [0004] Generally...
