Product Description

A Fuel Pressure Regulator is a component in a vehicle's fuel system that helps to maintain a consistent and appropriate fuel pressure throughout the engine's operation. The fuel pressure regulator is typically located on the fuel rail or in the fuel line and is responsible for controlling the pressure of the fuel that is delivered to the fuel injectors.

The Fuel Pressure Regulator works by using a spring-loaded diaphragm that reacts to changes in fuel pressure. When the fuel pressure is too high, the diaphragm opens and allows fuel to flow back to the fuel tank, reducing the pressure in the fuel system. When the fuel pressure is too low, the diaphragm closes, restricting the flow of fuel and increasing the pressure in the fuel system.

Daysyore offers a full range of Fuel Pressure Regulator designed to meet or exceed the OEM specifications, and has been tested and validated to ensure optimal performance and reliability.
