Diesel Fuel System Components

The diesel fuel supply components are critical to the proper operation of a diesel fuel injection system. They must supply the high-pressure injection components with extremely clean fuel, in sufficient amounts for proper operation under varying load and environmental conditions. Not only that, the system is so sensitive that if air is drawn into the supply of fuel, the engine will stop running. Filtration is important enough that two fuel filters are normally used in a two-step process to ensure the cleanliness of the fuel.
