Sumping fuel prior to every flight should be an indispensable part of every pilot’s preflight. When sumping a turbine jet, ease of use, and capacity are two features frequently requested, the Jet Sump takes care of those needs and then some. Made in the USA, the Jet Sump comes in a convenient compact storage design, the 4” extended neck reaches tricky recessed drain valves, and it meets the 32oz sampling requirement for Gulfstream Jets. Transparent design allows for a quick visual assessment of fuel quality. Measures 3.75” x 11.75” deployed, 3.75” x 8.25” when stowed. Weighs 1/2 a pound empty.
