b. Care and Handling. Observe the following precautions:
(1) Use care in handling components of the FARE as metal parts could cause personal injury.
(2) Use every effort to protect the FARE from the weather elements, dust, dirt, oil, grease, and acids.

1-10. General. For a formal refueling operation, the FARE is set up as shown in figure 1-7. Fuel from a
500-gallon collapsible drum is fed through a series o fconnecting fittings suction hoses and a butterfly valve to a
pump. The fuel then flows through a filter/separator, which filters out any impurities in the fuel. The filter-
separator also separates out any water that may have become mixed with the fuel through condensation or
contamination. The fuel then flows through a wye fitting to dispensing nozzles which are used to refuel aircraft.

Fuel stored in a 500-gallon collapsible drum is directed through an elbow coupler valve (1) and a
male-to-male adapter (2) into a 5-foot suction hose assembly (3).
The hose directs the flow to a butterfly valve (4) which operates as a shutoff valve and a fuel control valve.
When the valve is open, flow continues (through an additional 5-foot length of suction hose, if necessary) to
a tee fitting (5) which enables two fuel supply legs to enter the refueling operation.
Flow is then directed through an additional 5-foot suction hose to the engine-driven centrifugal pump
assembly (6).
The fuel under pressure from the pump is directed through a 5-foot suction hose assembly (3) to the
filter/separator (8) where contaminants are filtered out and water, if present, is separated and collected.
The engine/pump assembly and the filter/separator are connected by ground cables to a ground rod (7).
The output of the filter/separator is directed through the water detection adapter kit (9) and suction hose (3)
to a wye fitting (10).
The wye fitting (10) directs the fuel flow to two refueling points through a 50-foot discharge hose assembly
(11) and a closed-circuit nozzle (12). Each nozzle is connected through a ground cable to a ground rod. In
addition, each nozzle is electrostatically bonded to the vehicle being fueled by a grounding clip or plug.
