Abstract

Structure for installing a fuel level sensor in a fuel tank for automobiles, which can be applied as a common use regardless of the shape of the fuel tank and the model of a car and can prevent malfunctions of a warning light of the fuel level sensor caused by abrupt braking, abrupt accelerating, and cornering is disclosed. The structure is comprising: a post fixed upright on a drain plug of a fuel tank by a screw fit; a fuel level sensor that is installed on the end portion of the post.

Claims

1. A structure of a fuel level sensor in a fuel tank of an automobile, comprising:

a drain plug for draining fuel in the fuel tank of the automobile, disposed in a bottom wall of the fuel tank;

a solid post having a first end portion and a second end portion, the post being fixed upright on the drain plug with the first end portion;

a nut disposed proximate to the first end portion of the post against the drain plug; and

a fuel level sensor fixedly attached only to the second end portion of said post,

wherein the first end portion of the post includes a threaded portion and the drain plug includes a threaded bore configured to engage the threaded portion.

2. A structure of a fuel level sensor in a fuel tank of an automobile, comprising:

a drain plug for draining fuel in the fuel tank of the automobile, disposed in a bottom wall of the fuel tank;

a post having a first end portion and a second end portion, the post being fixed upright on the drain plug with the first end portion, a portion of the post being configured to adjust a height of the post; and

a fuel level sensor fixedly attached only to the second end portion of said post.

3. The structure of claim 2, wherein the post is fixed to the drain plug by a screw fit.

4. The structure of claim 2, further comprising a nut disposed proximate the first end portion against the drain plug.

5. The structure of claim 2, wherein the post being fixed upright on the drain plug is supported by means consisting of the drain plug.

6. The structure of claim 2, wherein the fuel level sensor includes a thermistor.

7. The structure of claim 2, wherein the first end portion of the post includes a threaded portion and the drain plug includes a threaded bore configured to engage the threaded portion.

8. The structure of claim 7, wherein the threaded portion and the threaded bore constitute the portion of the post being configured to adjust a height of the post.
