Abstract
A combined liquid and vapor sensor assembly includes a body and a mounting portion for coupling the body to a fuel pump module flange that defines an interface between an interior and an exterior of a fuel tank. A liquid pressure sensor is housed in a recess in the body for sensing a liquid pressure of a fuel in the fuel tank, and a vapor pressure sensor is housed in the recess in the body for sensing a vapor pressure of a fuel vapor in the fuel tank. An electrical connector is coupled with the body for providing power to the liquid pressure sensor and the vapor pressure sensor.
