A solid state fuel level sensor system disposed in a fuel tank according to one example of the present disclosure includes a first pressure sensor, a second pressure sensor, a reference chamber, a liquid discriminating membrane and a reference tube. The first pressure sensor is disposed in the fuel tank. The second pressure sensor is disposed in the fuel tank. The first and second pressure sensors are separated a vertical distance from each other in the fuel tank. The reference chamber is fluidly connected to the first and second pressure sensors. The reference tube is fluidly connected between the reference chamber and the liquid discriminating membrane. The reference tube extends into a vapor space of the fuel tank at the liquid discriminating membrane such that a vapor pressure at the vapor space is communicated into the reference chamber.
