BOTTOM LOAD (EXTERIOR PUMP -600 GPM)

In the operation above the tanker is filled from a reservoir which has its own pump able to transfer fuel

at rates up to 600 GPM. Receptacle A feeds directly into the tanker. The fuel can only flow through

receptacle A when valve V10 is open. Valve V10 opens as soon as the fuel pressure is available at

receptacle A unless the level of the fuel in the tank is at its maximum level. This serves as an automatic

shut-off so that when the fuel level rises to the full level valve V10 closes preventing the tank from being

over-filled.

NOTE

Refer to Figure 2-11 for tanker component identification.
