Doosan DL08 Fuel System Note

Doosan DL08 spans several emission versions and more than one common rail fuel system. This page locks only the reliably confirmed relationship: 0445120258 / 0 445 120 258 / 400903-0031 → Doosan DL08 / DL08K → common rail injector. Other DL08 injectors, high-pressure pumps and common rail components are treated as related DL08 products only; they are not mandatory matched parts for 0445120258. Always confirm by the number stamped on the existing injector, the engine and the machine information.
