In general, fuel injectors are nozzles responsible for delivering high-pressure fuel spray into your engine's combustion chamber. The sensor tells the fuel injector when and how much fuel should be delivered thousands of times. As a result, if you're in fleet management or the construction industry, you have machines that run on diesel. Diesel fuel injectors or 7.3 l power stroke diesel injectors are considered complicated, having a micron filter on the top inlet side corresponding to small holes in the bottom. The primary source of failures for injectors is the water in the fuel. Today, fuel injectors have evolved tremendously to be one of the highly efficient systems of modern-day automobiles. Working On Diesel Fuel Injectors Diesel fuel injectors tend to pressurize diesel fuel and pump it through an electronically controlled aperture. This delivers fuel to the engine as a spray, making it easier to ignite than a heavy stream. Remember that when fuel injection systems are no
