2.78.5 Fuel Sampling System. Fuel sampling is done with a thumb-operated handpump (Figure 2-24) containing 5 feet of plastic tubing. The tubing is placed in a guide tube inside the fuel tank and is directed to the bottom of the tank. The handpump is stroked and fuel is drawn from the tank, with contaminants at the bottom. When sampling is completed, the tubing is emptied, rolled, and stowed with the pump on the gravity refueling door.

Fuel sam-pling of the external extended range fuel system is done by taking the sample with a fuel sampler tube from the sump drain located at the bottom aft of each tank.
