Abstract

A fuel supply module is provided that includes a module body (B) formed from a mounting base (4), a fuel feed pipe (5), and a pump holding part (7) provided so as to be connected to a lower part of the mounting base (4), wherein the module body (B) is divided into a first block (B1) that includes the mounting base (4), a second block (B2) that includes the fuel feed pipe (5) and its boss (5a), and a fourth block (B4) that includes the pump holding part (7), a boss extension part (5b) extending downward from the boss (5a) is fitted into a support tube (4a) formed in the first block (B1), the support tube (4a) and the second block (B2) are welded, a third block (B3) is welded to an end face of the boss extension part (5b), the first and third blocks (B1, B3) are welded to each other, and the boss extension part (5b) and the third block (B3) are provided with first and second through holes (45, 46). It is thereby possible to provide at low cost a fuel supply module that includes a plurality of types of module bodies having, for example, different directions for a fuel feed pipe.

Description

technical field [0001] The present invention relates to a fuel supply module that mainly supplies fuel to a fuel injection valve of an engine, and particularly relates to an improvement of the fuel supply module as follows. The fuel supply module has a module body composed of the following components: The installation base is installed on the outer wall of the fuel tank; the fuel output pipe protrudes from the upper surface of the installation base; and the pump holding part is continuously provided on the installation base. The lower part of the seat holds the electric pump in the pump holding part, and the electric pump draws fuel in the fuel tank and discharges it to the fuel output pipe through the fuel passage. Background technique [0002] As disclosed in Patent Document 1, such a fuel supply module is known. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2007-291867 [0004] In the conventional fuel supply module of this type, since the module main body i...
