Fuel injectors are located in the intake manifold and spray fuel through a tiny nozzle. The fuel injector uses a special nozzle to spray the fuel as mist, instead of a strong jet stream. When the throttle valve opens, your fuel injector sprays fuel to mix with the air and then enters the engines combustion cylinders. Maintenance & Usage 1. Before using diesel parts, please carefully wash them in clean diesel.
