The GATS Jar fuel sampler allows you to put preflight fuel samples back into your airplane as an alternative to tossing fuel on the ground. This saves your dollars and is EPA friendly. Sample and check your fuel as always, then, as sampled fuel is returned to the tank, a unique, built-in screen separates solids and non-petroleum contaminants, so only clean, pure fuel is returned to the tank. Reversible sump actuator fits both pin and petcock actuators. Wide mouth collector helps protect hands and clothing. Resilient plastic construction makes the GATS Jar virtually indestructible with normal handling.
