A device to measure both the fuel level in high wing aircraft fuel tanks and check for water and other impurities in the fuel tanks. This invention is used from the underside of the wing and is inserted from below into the fuel tank sump valve. The device measures both the height of the fuel within the tank to determine how full it is and at the same time drains fuel into the device for visual inspection of water and other impurities. The device can be used to determine both fuel level and impurities at the same time or separately.

A guage to measure fuel level in the fuel tanks of high wing airplanes where the gauge used to measure fuel level has a mechanism which is activated by means of the fuel pressure against it and which in turn activates a pointer on a dial which indicates the level of fuel in the tank wherein the improvement comprises: (a) a hollow standpipe, with the upper end narrowing down to a perforated pin slightly smaller than the opening in the fuel tank sump valve, when the pin is pushed into the opening of the wing tank sump valve, and (b) which when pushed into the wing tank sump valve opens the valve sufficiently to allow fuel to flow into the opening in which the pin is inserted and through the perforations in the pin into the hollow standpipe while a collar fits tight against the opening in the valve preventing fluid from leaking out, and (c) and continues to flow down through the standpipe through the opening in the base where it presses against a pressure means mechanism with the full weight of the level of fuel in the fuel tank, and (d) which pressure means mechanism moves an indicator means registering the level of fuel in the wing tank, and (e) which measurement of the fuel level in the high wing fuel tanks is taken by inserting the device into the fuel tank sump valve while standing under the wing of the aircraft.
