4-16 Fuel Transfers - Cont'd.
WARNING
DRY PUMP SUCTION
Do not continue pumping after tank is empty. A dry suction can ruin the pump.
I.
Transfer Fuel from any Tank to the Switching Manifold
When called for, the fuel from any tank can be transferred to the switching manifold by connecting the discharge transfer
hose into the switching manifold and following the routing and transfer procedures outlined under "j" and "k" above. The
tie-in to the switching manifold can be made at most any point in the manifold desired (see Fig. 2-62) by disconnecting
the tee and valve (items 1 and 2 in the return manifold shown on Fig. 2-62) and connecting it in the aluminum pipe and
fitting train shown in either the standard or optional receipt manifold. The meter MS1 H can be inserted into the hoseline
if needed to register the quantity transferred. In this way, as determined by the operating management, the fuel can be
transferred to another fuel unit in the TPT or to the optional tanker-truck receipt manifold for outloading tanker-trucks. In
a multiple TPT installation connected to the same switching manifold, the fuel can be transferred to another TPT. In
planning these transfers to another fuel unit in the same TPT or to another TPT on the same expanded switching
manifold, consideration must be given to the possibility of cross contamination of different specification fuels. Obviously,
this should not take place in such a way as to cause cross contamination except in emergencies or special situations.
WARNING
PRESSURIZED SYSTEM
Do not break any flanges or open any couplings until the system is depressurized at that location. Injury and fuel spills
can result. Refer to paras. 4-17 thru 4-17. 5 for depressurizing procedures.
WARNING
CAP OPEN FITTINGS OR PIPE
Cap off open fittings or pipe in return manifold to minimize the risk of unintended flow from another fuel unit causing a
spill to the return manifold.

Load Out Tanker-Trucks at Tanker-Truck Receipt Manifold
Fuel from any tank can be loaded out at the tanker-truck receipt manifold by disconnecting valve V35J from the return
manifold to the associated pipeline (Fig. 2-62) and coupling it to the hoseline from the tanker-truck receipt manifold that
normally connects at valve V 13TJ (or V13TM, or V13TD, depending on the service). Although the procedure outlined
above appears to be the most practical, the procedure described under "n" of tying V35J back into the switching manifold
will accomplish the same thing and permit discharge to the tanker truck receipt manifold. In either case, the meter MS1
H can be installed in the transfer hoseline if desired. Assuming the first flow path noted above is selected, the load out
procedure is as follows:
