1-27. M978 TANKER.

(fig. 1-21) The tanker maybe loaded through the manhole (1) in the top or by

using the loading valve (2) in the bottom of the tank. A hydraulic motor driven pump (3) is used to deliver

fuel during all fueling operations. An electric motor driven pump (4) serves as a backup pumping unit in

case the tanker loses hydraulic power. Fuel delivery hoses are stored on retracting reels (5) located on each

side of the fueling station. Two reel mounted static grounding cables (6) are provided for grounding

whatever is being fueled or defueled. An emergency shutoff valve and a hand-actuated deadman control

are included for greater safety. Hand-operated valves attached to the delivery hoses control fuel flow

during refueling.
