Abstract

A fuel level measuring system for a liquid fuel tank may utilize a primary sender gage assembly employing at least a primary sender gage, a primary sender arm, and a primary sender float. The system may further utilize a secondary sender gage assembly employing at least a secondary sender gage, a secondary sender arm, and a secondary sender float. A dash indicator may display a fuel level of fuel within the fuel tank based upon resistances from the sender gages. The primary sender float and the secondary sender gage are contained within a single unit that is buoyant in liquid fuel. The fuel tank may have a top dome portion and a bottom dome portion that the secondary sender float is capable of occupying while the sender gages transmit a signal corresponding to fuel levels in the tank.
