Abstract
A fuel tank system for use in a vehicle comprises a fuel tank having a volume comprising a first or primary range and a second or preliminary range. A fuel level sensor assembly disposed in the fuel tank comprises a receiving unit, a first fuel level sensor positioned to move with the level of fuel in the first or primary range of the fuel and a second fuel level sensor positioned to move with the level of fuel in the second or preliminary range of the fuel. The receiving unit delivers a signal to a control module that indicates that the fuel level is within the preliminary range or the primary range.
