Abstract
A method and apparatus for measuring low fuel level in a fuel tank having a fuel pump with an anti-slosh pot supplied with fuel from a predelivery pump in the fuel pump. Fuel measurement is effected by sensing delivery of air to the anti-slosh put by the predelivery pump when the fuel level in the tank is low, and measuring the amount of fuel in the anti-slosh pot when delivery of air is sensed. The amount of fuel measured in the anti-slosh pot accurately represents the amount of fuel remaining in the fuel tank.
