e. Fuel Sampling. (Refer to figure 2-18)
It is mandatory that the performance of filter-separator on all aircraft refueling equipment be checked every
30 days through the submission of samples taken from the effluent stream of the filter-separator.
Do not allow fuel to come in contact with eyes or skin. Wear protective goggles. Fuels are toxic
and can cause illness or death. If fuel contacts skin or eyes, flush and get medical attention
The adapter assembly (1) attached to the filter-separator's outlet coupling (2) contains a sampling probe
(3), which extends into the fuel flow. A Detector Kit, NSN 6640-00-244-9478, can be attached to the
sampling probe (3) to obtain fuel samples.
For disposal of contaminated fuel, refer to FM 10-20.
