Fuel-Handling Vehicle Fuel-handling vehicles are classified as fuel tank trucks  or  fuel  tank  semitrailers.  Each  vehicle  has distinguishing   characteristics   (model,   size,   and capacity). The purpose of fuel-handling vehicles is to load, haul, and discharge fuel to other vehicles, aircraft, or  fuel  depots. DESCRIPTION.—  A typical fuel tank truck is equipped with a tank body divided into compartments. Each  compartment  has  a  manhole  and  filler  cover assembly,  bottom  sump  or  well,  and  discharge  valves with  screen  assemblies  and  drainpipes.  The  drainpipes end in a manifold in the equipment Compartment. The compartment (fig. 6-19) also houses a delivery pump, a discharge valve control assembly, a pump delivery line gate valve, an automatic dump valve, drain tube valves, a gravity line gate valve, a filter separator, a pressure gate,  a  meter,  a  water  separator  chamber,  and  a grounding cable. The  delivery  pump  is  powered  by  the  power  takeoff (PTO), which is controlled by the PTO lever located in the cab of the truck. The lever is moved backward to the  ENGAGED  position  to  engage  the  PTO  which causes the pump to operate. The lever is moved forward to the DISENGAGED position to disengage the PTO and to stop the pump. The discharge valve control assembly levers control the discharge valves located at the bottom of each tank Figure 6-19.-Dispensing equipment compartment. 6-25
