The fuel system stores, filters, pressurises and delivers fuel to the combustion chamber at the right moment and in the right quantity. This group covers injectors, high-pressure and transfer pumps, fuel rails, filters and water separators, and low-pressure lines. The DL06 and later Doosan engines use electronically controlled common rail injection meeting Tier 3 and later emissions standards, which brings tight tolerances and a low tolerance for contamination. Machines working from bulk or drum fuel supplies are particularly exposed to water and particulate ingress, and injector or high-pressure pump failure on these engines almost always traces back to fuel cleanliness rather than component defect.
AMS Parts supplies a wide range of fuel system components for Doosan engines used in power generation, marine, and industrial applications. Browse the full range below, or contact us for specific requirements.

Water and particulate contamination in the fuel is the dominant cause. Machines fuelled from bulk tanks or drums are most exposed, so water separator maintenance is critical.
Many can be overhauled and flow-tested by a specialist. Testing matters because fuelling must be matched across the set for even running.
Hard starting, rough running, power loss under load, smoke, and in severe cases a no-start. Rail pressure readings help distinguish supply faults from injector faults.
