Shop 5.9 Cummins Parts by Application

The 5.9L Cummins engine has several applications, so application information is crucial when you are looking for replacement parts.

12 Volt Cummins Applications

Previous 5.9L engines use a mechanical fuel system, which means you need a P7100 injection pump. We offer components for selected earlier applications, including the 5.9 Cummins injection pump used with compatible engines.  We recommend learning more about your engine configuration before replacing a fuel system component.

24 Volt Cummins Applications

The introduction of 24V 5.9L engines changed fuel systems. Our parts include 24V injectors and some other fuel system parts for selected years. For these engines, the correct injector or fuel system part depends on the application. You can narrow your choices by finding out the year range of the application and what parts you already have.

Common Rail 5.9L Applications

Some late 5.9L engines use a common rail fuel system. Our parts include CP3 injection pumps, MPROPS, fuel rails, pressure sensors, feed tubes, supply pumps, and application-specific injectors. Identifying common rail applications can simplify your search for 5.9 Cummins diesel parts.

5.9 Cummins Fuel System Parts

Fuel delivery is more than just the fuel injector. The fuel pump, fuel rail, fuel pressure components, fuel feed tubes, and supply system each play a unique role. We offer 5.9 Cummins fuel system parts that include:

• Injection Pumps: P7100 and CP3 models for certain applications.

• Fuel Injectors: Fuel injectors for various 5.9L engines.

• Fuel Rails: Certain common rail applications.

• MPROPs: Metering parts for certain 2003-2007 applications.

• Fuel Pressure Sensors: Application-specific pressure sensors.

• Fuel Supply Pumps: Parts for certain 2003-2004 applications.

• Fuel Injection Tubes: Additional fuel delivery parts.

• Fuel Injector Installation Kits: Related parts for certain injector applications.

5.9 Cummins Injectors & Injection Pumps

The injectors and injection pumps are some of the most application-dependent parts of a 5.9L Cummins fuel system. We offer several alternatives because older mechanical engines and newer common-rail engines use different fuel systems. We offer a selection of 5.9 Cummins injectors for select 24V and common-rail applications. Also, we supply P7100 and CP3 injection pumps for certain engine applications.

If you work on common-rail engines, we offer CP3 MPROPs, fuel rails, pressure sensors, and injector feed tubes. Such additional components can be necessary for your fuel system rebuild. For performance builds, we supply the following 5.9 Cummins performance parts for certain engine applications. In these cases, start with your engine application and purpose.

How to Identify Your 5.9 Cummins Engine

We suggest that you gather some information about your truck and engine before making your order.

Check Truck's Model Year

Your truck's model year will help you determine the correct application for the 5.9L engine. Some parts from our assortment are marked by years.

Check Engine Configuration

Find out whether your engine is the older 12V, 24V, or common rail 5.9L Cummins engine. It is especially useful when choosing injectors or injection pumps.

Check the Type of Fuel System

Mechanical fuel systems and common rail fuel systems use different parts. It is useful to know what type of fuel system you have.

Check the Old Part

If you're replacing a component, compare its number and configuration with the new one. This gives you more references when checking the replacement list.

Check Product's Application

Once you have enough information about your engine, check it against the product's application.

How to Choose the Right Part

We suggest starting with the engine instead of the part name. Once you've identified the 5.9L setup, you will have a clear idea of which components are compatible.

First, identify the engine generation. Determine whether your truck has a 12V, 24V, or common-rail 5.9L.

Next, confirm the model year. Use the year range to narrow the available products.

Then, identify the component. Decide whether you need an injector, injection pump, fuel rail, MPROP, sensor, supply pump, or another fuel-system component.

Compare the existing part. Check the current component and part number where possible.

Consider the intended use. If you are upgrading your truck, make sure any performance component fits your engine configuration.

Verify the application before ordering. Review the product details and make sure the listed fitment matches your engine.

Find the Right 5.9L Cummins Component

We simplify your selection process by focusing on the engine configuration, application, and the specific part you need. Whether you are changing injectors, servicing your fuel system, or replacing your injection pump, fitment accuracy is always the first step.
