Genuine BOSCH Pressure regulator
Part number 0281006074

A fuel pressure regulator is a crucial component in a car's fuel system. It is responsible for maintaining a consistent and optimal fuel pressure for the engine. The regulator controls the flow of fuel from the fuel pump to the fuel injectors, ensuring that the correct amount and pressure of fuel is delivered to the engine at all times.

The fuel pressure regulator acts as a valve that regulates the pressure in the fuel lines. It uses a diaphragm and a spring mechanism to control the fuel pressure. When the fuel pressure exceeds the desired level, the regulator restricts the flow of fuel, allowing excess fuel to return to the fuel tank. Conversely, when the fuel pressure drops below the set level, the regulator opens up to increase the flow of fuel. This continuous adjustment by the fuel pressure regulator helps maintain proper fuel pressure, ensuring smooth engine performance and efficient fuel combustion.
