4-16 Fuel Transfers - Cont'd.
WARNING
NO SMOKING
Enforce no smoking rules on all personnel, including drivers from outside the TPT.
WARNING
VEHICLE DISCONNECT
Make sure vehicles are disconnected from the dispensing assembly before moving.
WARNING
STOP VEHICLE ENGINES
Stop all vehicle engines while loading.

Transfer Fuel from a Primary Module Tank to the Associated Pipeline System.
To transfer fuel from the TPT to the associated pipeline, there must be no back pressure in the pipeline system that
exceeds the 600 gpm hoseline pump's discharge head capability. This relative pressure situation will vary with the
specific system and cannot be fully described here for a typical installation. The 600 gpm hoseline pumps are restricted
to a discharge pressure of 150 psig. The hoseline system is restricted to 150 psig maximum pressure. Assuming the
specific installation and its associated pipeline system are set up such that this can be done, the operating instruction for
transferring fuel from tank TSJ via pump P3J to the associated pipeline system is as outlined below. The routing and
procedures to transfer from T6J or through P4J would be the same except for the valve positions between the tank and
pump and the cross assembly. See P&ID flow diagram, Fig. 4-1.
1.
Open valves V40J, V41J, V42J, V43J, V44J, V451, V46J, V38J, V37J, V36J, V32J, V30J, V29J, and V33J.
2.
Record reading or reset meter MS1H.
3.
Start and operate pump P3J at low discharge pressure.
4.
Open V35J while increasing the discharge rate on pump P3J.
CAUTION
BACK FLOW
Make sure there is no flow from pipeline system into the TPT when the intent is to transfer from the
TPT to the pipeline system.
