TM 10-3835-231-13
(8) When the TPT is to be used for multiple fuels, purge and fill each fuel unit individually to avoid any cross
contamination.
(9) Purge and fill fuel unit as follows. (See figure 2-24.)
NOTE
Each fuel unit is purged and filled using the same procedures.
(a) Connect tanker-truck to receipt manifold at valve (1).
(b) Open valves (1), (2), (3), (4), (5), (6), (7); also open valves (8), (9), (10), and (11).
(c) Isolate the TPT from the pipeline by closing the first valve upstream of the switching manifold
(d) Purge and fill supply hoselines to the contaminated fuel module:
1 Open valves (12) and (13).
2 Start pump (14) and open valve (15) slowly. Place a container under coupling connected to valve
(17). Open valves (16) and (17) until fuel comes out then close valves; this will purge air from line.
3 Repeat the procedure with valves (18), (19), (20), and (21).
4 Close valves (18), (19), (20), and (21).
5 Air and vapor will flow into tank (22) and through its vent.
6 When a steady flow of liquid can be heard and the venting rate has dropped, open valve (23)
slowly and purge into tank (24). Close valve (15).
7 When a steady flow of liquid into tank (24) can be heard and the venting rate has dropped, close
valves (13) and (12).
8 Stop the pump (14).
9 Close valve (23).
(e) Purge and fill supply lines.
1 Open valves (25), (26), and (27).
2 Start pump (14).
