runs from the filter/separator to the manifold, and product can be discharged from the manifold outlet when
the three-way valve issued to close off the suction side. Other models use the only manifold for suction.
Hose reels. The dispensing hoses are stored on two hose reels, each with a recoil tension spring. A 40-foot
length of 1 1/2-inch, noncollapsible discharge hose is used on each reel. Product from the filter/separator
enters through a pipe at the hub of the reel and is discharged through the hoses.
Ground reel. A ground reel is attached to the frame of the pumping assembly so that the tank and pump
unit can be grounded. One section of the ground wire must be clipped to a ground rod near the tank and
pump unit before the other section is connected to the vehicle being fueled.
Metering kit. The metering kit consists
of a meter, hose assembly, couplers, cap screws, and washers. The
kit is used with pumping assemblies on all tank and pump units.
Other items. Other items issued with the pumping assembly are a drum-unloaded suction stub for emptying
55-gallon drums, two dispensing nozzles, a starter rope, a carbon dioxide fire extinguisher, and tie down
assemblies. If the nozzles have lock-on, latch-open devices, the devices must be fixed so that they must be
held open by hand and attended at all times.
PART B - GAGING PETROLEUM TANK VEHICLES
Each tank has its own gage stick, which is graduated in 25-gallon divisions. It may be made of wood or
metal depending on the type of vehicle. The only difference in use between this stick and the petroleum gage
stick is that the product cut will be recorded in gallons. It is important that your personnel keep the stick
protected from the elements whenever not in use. Personnel will need to estimate the indicated volume as
closely as possible when the cut mark falls between the 25-gallon divisions. The 5,000-gallon tank
semitrailers have gage sticks marked at the top to show which scale to use for each tank compartment.
Before gaging any type of vehicle, the vehicle must be on level ground, and you must ensure that personnel
bond and ground the tank vehicle and ground themselves from static electricity by touching a bare hand to
the tank shell. Personnel should not wear loose items when they are on top of the tank vehicles. Personnel
should never gage during an electric storm. Personnel should position the fire extinguisher within 10 to 15
feet of the tank vehicle. Verify the shipping document for the kind of fuel in the tank vehicle. Personnel
should insert the thermometer as soon as they open the hatch. (If quantity is less than 3,500 gallons, it is not
necessary to take the temperature.) Personnel should gage the compartment and take an all-levels sample.
Ensure that personnel measure the API gravity of the sample and record it on the gage work sheet.
Personnel should correct the volume to 60 degrees Fahrenheit when required.
PART C - REFUEL-ON-THE-MOVE CONCEPT
The "doctrinal purpose" of ROM is to extend the time that ground maneuver forces can spend on the
objective, although ROM can be tailored to other situations as well. Refuel-on-the-move (ROM) for ground
vehicles is synonymous with rapid or hot refueling for aircraft. ROM is normally accomplished as far forward
on the battlefield as the tactical situation permits, prior to the tactical assembly area. When vehicles enter a
ROM site (Figures. 3-7) for refueling, they receive a predetermined amount of fuel (usually timed) and move
out to return to their convoy or formation. This distinguishes it from routine convoy refueling operations. The
manner in which this refueling is done depends upon the tactical situation. Each refueling operation is unique
depending on the number of vehicles to be refueled, the distance the unit is traveling, and how many times
the unit wants to be refueled. However, the assembly and operation of each ROM are basically the same.
Due to safety considerations, normal vehicle refueling is done with engines off.
PART D - COMPONENTS OF THE ROM
The following components make up the ROM kit :
3 each, 14' X 4' suction hose
8 each, 50' X 3' discharge hose
8 each, 25' X 1 1/2' refueling hose
