Spring - Pressure Relief Valve for Fuel Pump
Detroit Diesel

This steel pressure relief valve spring, with a free length of 50.29 mm and an outer diameter of 6.10 mm, is designed to control fuel pressure regulation in the engine’s fuel pump system. Its specific wire diameter of 0.86 mm provides the necessary tension to maintain consistent pressure, preventing over-pressurization that could damage components or impair performance. The spring’s resilient steel construction ensures longevity and reliable operation over many cycles. It works by compressing or decompressing in response to pressure changes, ensuring stable fuel delivery. Proper functioning of this spring is crucial for engine efficiency, emissions control, and fuel economy. Maintenance of the fuel system often involves replacing this spring to preserve operational stability.
