Replacement REPB670501 Fuel Filter with Integrated Pressure Regulator

The Replacement REPB670501 is a direct-fit fuel filter featuring an integrated fuel pressure regulator, designed as an aftermarket OEM-style replacement for the BMW 3-Series (2001–2006). This combination unit simplifies the fuel system service process by replacing the filter and regulator in a single component.

The fuel filter removes contaminants and debris from the fuel supply before it reaches the injectors, while the built-in pressure regulator continuously controls fuel pressure based on intake manifold vacuum — routing excess fuel back to the tank and ensuring the engine receives a consistent, optimal fuel supply under all operating conditions.

Key Features:

• Integrated fuel pressure regulator for simplified installation and service
• Direct OEM-style replacement — designed to match original fit and function
• Approximately 2.17-inch diameter, 0.31-inch inlet, 0.31-inch outlet, 12.40-inch overall length
• Helps restore proper fuel flow and engine performance
• Manufactured to meet aftermarket quality standards

Regular fuel filter replacement is recommended every 60,000–80,000 miles to prevent clogging and maintain consistent fuel delivery. Symptoms of a failing fuel filter or pressure regulator can include reduced acceleration, rough idle, and increased fuel consumption.
