Fuel system plays an important role of supplying fuel to the engine. The fuel system in a GMC Sierra diesel has got many components and this includes fuel filler pipe, fuel tank, fuel pump, fuel filter and fuel injector. You need not be a technical person to understand the working of the fuel system. It is very simple.

On getting filtered through the fuel filter, the fuel enters the fuel pump from where it is pumped at high pressure to the fuel injector.
Diesel fuel injector is a small yet powerful device which helps the engine receive right amount of fuel at right time. Diesel fuel injector is responsible for injecting diesel at high pressure into the cylinder filled with hot compressed air for combustion. As a device fuel injector is a small electronically controlled valve. This small valve open and closes several times to allow the diesel into the cylinder. GMC Sierra diesel injector valve is opened with the help of electromagnet stop. The pressurized fuel is squirts out through the nozzle. When the diesel comes out of the nozzle it is atomized and sprayed as a mist evenly into the cylinder.
