Overflow Valve - Fuel Filter OM904 Euro 4/5
Detroit Diesel

The overflow valve used in OM904 Euro 4/5 fuel systems is engineered to regulate fuel pressure within the filter assembly, maintaining a consistent 50 bar operating pressure. With an outer diameter of 1.05 inches and an overall length of 2.44 inches, it threads into the fuel filter assembly with an M16X1.5 mm thread. Constructed from durable steel, this component is designed to withstand high-pressure environments and temperature fluctuations ranging from -40°C to +125°C. Its precise operation prevents excess pressure buildup, protecting the fuel system and engine components from damage. Proper installation and high-quality replacement parts from reputable sources like Source One Parts Center ensure reliable fuel delivery, optimal engine performance, and compliance with emission standards, especially critical in heavy-duty applications where fuel system integrity is paramount.
