(1) Check the level of water in the tank. It must at least fill the pipes and emergency valve. If not,
open the emergency valve and fill through the top opening using a bucket.
(2) Close the emergency valve. Close both gravity discharge valves and any other outlet.
(3) Attach the inlet hose to the discharge valve (either side) and connect the other end to the source.
(4) Attach the outlet hose to the discharge valve on the pump and place the other end in the top
opening on the tank.
(5) Start the engine. Open the discharge valve on the pump first and then open the gravity discharge
valve (source inlet) immediately.
(6) Fill the tank and close the gravity discharge valve when the tank is filled. Shut off the engine
and disconnect all of the hoses.
c. Filling the M1098 Tanker From a Source Under Pressure or Using an External Pump. Ensure your
subordinates properly supervise tanker filling from a source under pressure or using an external pump. Soldiers
must
(1) Attach the inlet hose to the gravity discharge valve (either side) with the other end connected to
the source or the external pump.
(2) Open the gravity discharge valve and open the emergency valve (dump valve).
(3) Fill the tank and close all of the valves. Disconnect the hoses once the tank is filled.
PART C - FAWPSS OPERATIONS
1. FAWPSS components are lightweight and air transportable. They can be delivered by parachute airdrop, or
sling loaded and delivered by an Army utility helicopter. The FAWPSS is also transportable by ocean cargo
ship, rail car, standard military 5-ton cargo truck, or a semitrailer.
2. The FAWPSS is operated by a 125-GPM centrifugal pump. Six 50-gallon water storage and dispensing
drums are attached and replaced, two at a time. The rationale for authorizing six drums is based on two drums
being filled while two are being transported and two are being used with the system. Quick-disconnect
couplings connect the drums to the balance of the system. These drums provide water by the suction of the
pump through drums. The six water drums are designed for a working pressure of 4 to 5 PSI. It can be towed,
at speeds not to exceed 10 MPH for short distances over smooth terrain using the towing and lifting yoke.
3. This system can prove to be a valuable asset for your unit. The HEAT or sometimes referred to as EAT
method of carrying cargo and equipment overcomes many of the obstacles that hinder other modes of
transportation. The EAT method of movement with its ability to bypass surface obstacles, provides rapid
movement of supplies and equipment. With the use of aerial support, the FAWPSS can be used to supply an
isolated unit, or one that has been cut off from routes of communication. Procedures for requesting aerial
support will depend on whether the mission is
