ABSTRACT:
A fuel tank level indicator for indicating at a surface when a fuel tank is filled with fuel, such indicator installed on a fuel inlet pipe and having a loop pipe in line with the inlet pipe with a riser pipe at the top of the loop and a float member disposed in the riser pipe to raise an indicator member above the surface when the loop pipe fills with fuel. The fuel is prevented from backing up the inlet pipe by a back flow preventor and some of the fuel then passes into the riser pipe, raising the float member and its attached indicator member above the surface where it is visible by the person entering fuel into the inlet pipe who will then see the indicator member and stop the flow of fuel.
