ABSTRACT:
An apparatus for indicating the amount of fuel in a fuel tank for a barbecue grill is disclosed. The apparatus includes a first housing member having indicator marks on an indicator wall thereof, a second housing member slidably engaging the first housing member and further securing the fuel tank, and a spring member connected to the first and second housing members to provide a resistive force to oppose the downward movement force of the fuel tank. The second housing member has a gauge wall with openings such that the gauge wall at least partially overlies the indicator wall of the first housing member to progressively expose indicator marks through the openings. The exposed indicator marks provide a readout of the amount of fuel remaining in the fuel tank.
