Bosch Fuel Pressure Regulator

The Bosch fuel pressure regulator (also called a fuel injection pressure regulator) keeps fuel pressure in the fuel rail steady relative to intake manifold conditions. Steady pressure helps the injectors deliver a consistent amount of fuel. That supports smooth idle, responsive acceleration, and efficient combustion.

Key Features:

• Regulates fuel system pressure to help maintain proper fuel delivery across operating conditions
• Diaphragm-based design that responds to changes in engine load and manifold vacuum or pressure
• Returns excess fuel to the tank to help maintain a stable pressure level
• Built with fuel-resistant materials suited to demanding under-hood environments
• Engineered to meet Bosch's quality standards for fuel injection components

Bosch is a long-established supplier of fuel injection technology and original equipment components. A properly working regulator helps protect injectors and the fuel pump from pressure-related wear. Choose the variant that matches your application from the options listed on this page.
