BULK UNLOAD (FILTERED)

In this operation the tankers fuel is being pumped out by the vehicles own pump. Fuel leaves the tank by

valve V1 and flows to the pump. From there it goes through V5 and then to the FS (Filter-Separator).

Filtered fuel then flows through valve V6 (Fuel/Defuel Valve) which routes it through the flow meter, V11

flow regulator valve, and onto receptacle D.

NOTE

Refer to Figure 2-11 for tanker component identification.
