Fuel Rail: Description and Operation
Fuel Rail
The fuel rail is mounted to the top of the engine and distributes fuel to the individual injectors. Fuel is delivered to the fuel inlet tube of the fuel rail by
the fuel lines. The fuel goes through the fuel rail to the fuel pressure regulator. The fuel pressure regulator maintains a constant fuel pressure at the
injectors. Remaining fuel is then returned to the fuel tank.
