Fuel Rail

Fuel Rail Assembly:

The fuel rail assembly is made up of two rails and carries the fuel injectors, the left hand rail, delivers fuel to the even cylinders (2,4,6) and the right hand rail delivers fuel to the odd cylinders (1,3, 5).

Fuel is delivered to the fuel inlet tube of the fuel rail by the fuel pipes. The fuel then goes through the fuel rail to the fuel pressure regulator. The fuel pressure regulator maintains a constant fuel pressure at the fuel injectors. Remaining fuel is then returned to the fuel tank.
