Abstract

A fuel storage assembly for a vehicle includes a fuel tank defining a fuel chamber, a fuel pump module and a vapor pressure detection system. The fuel pump module includes a flange engaged to the fuel tank and a fuel pump assembly supported by the flange and disposed in the fuel chamber. The vapor pressure detection system includes a vapor pressure sensor attached to the flange, a vapor pressure inlet device disposed in the fuel chamber, and a conduit communicating between the vapor pressure inlet device and the vapor pressure sensor.

First claim

What is claimed is:

1. A vapor pressure detection system for a vehicle fuel tank comprising:
a fuel vapor permeable membrane;
a vapor pressure sensor;
a tube extending between the fuel vapor permeable membrane and the vapor pressure sensor providing at least in-part communication between an inlet end segment of the tube and the vapor pressure sensor, wherein the fuel vapor permeable membrane generally covers at least a portion of the inlet end segment of the tube; and
a flange constructed and arranged to be attached to the vehicle fuel tank, wherein communication between the inlet end segment of the tube and the vapor pressure sensor is through the flange, wherein the vapor pressure sensor includes an encasement having an electrical connection portion and a nipple portion extending through the flange for connection to an outlet end segment of the tube opposite the inlet end segment.

2. The vapor pressure detection system set forth in claim 1 , wherein the vapor pressure sensor is attached to the flange.

3. The vapor pressure detection system set forth in claim 1 , further comprising:
a birdcage structure attached to the inlet end segment, wherein the vapor permeable membrane covers the birdcage structure.

4. The vapor pressure detection system set forth in claim 1 , wherein the vapor permeable membrane is generally impermeable to liquid.
