The Cummins ISC fuel system is responsible for delivering fuel to the engine’s cylinders. It is a complex system that consists of several components, including a fuel tank, fuel lines, fuel filters, fuel pump, fuel injector, and engine control module (ECM).

The fuel system works by drawing fuel from the fuel tank and delivering it to the fuel injector. The fuel injector then sprays the fuel into the engine’s cylinders, where it is mixed with air and ignited by the spark plug.

Fuel Injection System

The Cummins ISC fuel injection system is a common rail system. This means that fuel is delivered to the fuel injectors at a high pressure, which allows for precise control over the fuel injection process.

The fuel injectors are electronically controlled by the ECM. The ECM opens and closes the fuel injectors at the appropriate time to ensure that the correct amount of fuel is delivered to the engine’s cylinders.

Fuel Filtration and Supply
