This allows the fuel samples to be returned to the aircraft instead of being thrown on the ground. After the water is trapped in the container, and the fuel is back in the tank, the captured water can then be thrown on the ground without polluting the soil, and the ground water with leaded fuel.
The GATS jar comes packaged in a reusable plastic bag. Save this bag to put the tester into after each use, when it is stored in the cabin during flight.
How the GATS Jar works
The separator screen is made of a material that when coated with petroleum based fuels creates a barrier to the passage of water through it, but remains no obstacle to the flow of fuel. It is important to tip the tester only far enough to pour the fuel out through the screen, but not so far that the liquid level ever goes above the top of the screened opening.
To work properly the separator screen must be coated with fuel before it is exposed to water. If water should impregnate the screen it must be removed before it can be used for fuel purification. To clear the separator screen of water, use a dry absorbent tissue or cloth and wipe the top of the screen surface thoroughly.
The separator screen works equally well with jet fuel, or AVGAS. The screen mesh also provides particulate debris filtration to approximately 200 microns.
WARNING...If the separator screen is damaged, do not use the tester.
