Genuine BOSCH Distributor Tube
Part number 0445224055

A fuel rail in a car is a crucial component in the fuel delivery system. It is a metal tube that circulates fuel to the fuel injectors, which are responsible for spraying fuel into the engine's combustion chambers. The fuel rail receives pressurized fuel from the fuel pump and distributes it evenly to each fuel injector. It acts as a conduit, ensuring a continuous and controlled flow of fuel to the engine.

The fuel rail also plays a role in regulating fuel pressure. It typically contains a pressure regulator that maintains the desired fuel pressure within the system. The pressure regulator is designed to sense the pressure in the fuel rail and adjust the flow of fuel accordingly. This helps to optimize the performance and efficiency of the engine by delivering the correct amount of fuel at the right pressure. Overall, the fuel rail ensures the proper distribution, pressure, and flow of fuel to the engine, contributing to smooth operation and power output.
