Abstract

In a pressure sensing device for a fuel tank, a mounting member for mounting a fuel pump is provided with a pressure detecting opening. A base member is fixed to the mounting member through a seal member. A pressure sensor is mounted on the base member. Accordingly, the installation to the fuel tank can be facilitated and the number of parts can be decreased, thereby increasing production efficiency.

Claims

1. A pressure sensing device for a fuel tank, comprising:

a mounting member for mounting a fuel pump to said fuel tank, said mounting member being provided with a pressure detecting opening and a sensor mounting portion, said sensor mounting portion being molded integrally with said mounting member;

a pressure sensor for detecting an internal pressure of said fuel tank through said pressure detecting opening, said pressure sensor being mounted on said sensor mounting portion; and

a cover provided at said sensor mounting portion so as to cover said pressure sensor.

2. A pressure sensing device for a fuel tank according to claim 1, wherein said mounting member is provided with a recess, and said pressure detecting opening and said sensor mounting portion are provided inside of said recess.

3. A pressure sensing device for a fuel tank according to claim 2, wherein said cover is provided with a connector for external connections, and said connector is projected to the outside of said recess.

4. A pressure sensing device for a fuel tank, comprising:

a mounting member for mounting a fuel pump to said fuel tank, said mounting member being provided with a recess;

a pressure introducing nipple joined airtightly to the bottom portion of said recess of said mounting member;

a pressure sensor for detecting an internal pressure of said fuel tank through said pressure introducing nipple, said pressure sensor being disposed in said recess; and

a cover provided at said mounting member so as to cover said recess.

5. A pressure sensing device for a fuel tank according to claim 4, wherein said cover is provided with a connector for external connections, and said connector is projected to the outside of said recess.
