Abstract
A filler tube assembly is used with a fuel pump nozzle having a pressure sensing port. The filler tube assembly includes a receiver having an inner wall defining an aperture, which receives the pump nozzle. The inner wall defines an orifice and a seal is coupled to the inner wall about the orifice for defining a chamber between the inner wall, the seal, and the fuel pump nozzle when the fuel pump nozzle is disposed in the aperture. A vacuum tube has a coupled end in fluid communication with the orifice and an open end in fluid communication with the fuel tank. The receiver defines a rim for seating the fuel pump nozzle in the aperture to align the pressure sensing port with the orifice. When fuel covers the open end of the vacuum tube, a pressure change is transmitted through the filler tube assembly to the pressure sensing port.
