Numbers match the table below; each box is one top-level part or assembly with what it contains.

#	Part	Qty	What it does
1	Fuel Tank	1×	Integrated or stand-alone tank storing 10,000+ L of marine diesel or HFO.
2	Fuel Lift Pump	1×	Electric transfer pump drawing fuel from tank to the injection system.
3	Fuel Filter	2×	Cartridge filter (20 µm nominal) removing dirt and water from fuel.
4	Fuel Injection Pump	1×	Rotary or inline pump generating high-pressure fuel (1,600–2,500 bar).
5	Common Rail	1×	High-pressure accumulator pipe supplying fuel to all injectors at constant pressure.
6	Fuel Return Line	1×	Pipe returning excess fuel and cooling flow from injectors to the tank.
7	Fuel Pressure Regulator	1×	Pilot-operated valve maintaining rail pressure independent of engine load.
