This is a domestic replacement for the Mann PL271/1 water-oil separation diesel filter. Its dimensions and performance parameters are benchmarked against Deutz OEM part numbers 04504438 and DZ04504438. Integrating dual functions of diesel filtration and water-oil separation, it effectively removes water, impurities and gums in diesel fuel. It protects precision fuel components such as injectors and high-pressure fuel pumps, reducing risks of wear, corrosion and sticking in the fuel system. Compatible with Deutz engine units, it serves as a direct replacement for OEM filters with simple installation, ideal for long-term operation of construction machinery and generator sets.
