Abstract
A device (10) for testing samples of aviation fuel drained through a drain valve of an aircraft fuel system is disclosed including a pin (22) upstanding from the bottom (18) and extending concentrically with the sidewall (16) out of and above the inlet (20) of a container (12). Thus, the fuel draining from the drain valve is caught and collected by the inlet (20) and is contained in the container (12) for visual observation for particulate contamination and liquid separation. Device (10) further includes specific gravity floats (32, 34) having densities to float in water but not in jet fuel and gasoline and to float in water and jet fuel but not in gasoline, respectively. Thus, by observing the condition of the floats (32, 34), the pilot can quickly, accurately, and clearly determine whether the sample is gasoline, jet fuel, or water. Device (10) further includes a screen (36) anchored to the sidewall (16) of the container (12) adjacent the inlet (20) for preventing passage of the floats (32, 34) from the container (12) through the inlet (20) while permitting generally unrestricted flow of liquid into the container (12) through the inlet (20). In the most preferred form, pin (22) u…
