Fuel Related | 2019-2024 Ram 6.7 Cummins

If you’re looking to protect your fuel system, add horsepower, or just keep your Cummins running strong, we’ve got you covered. Diesel Power Products stocks a wide selection of fuel-related parts for 2019–2024 Ram 6.7 Cummins trucks, including lift pumps, injection pumps, performance injectors, filtration systems, and fuel additives. Whether you’re stock or tuned, these upgrades help ensure your fuel system performs reliably and efficiently.

Starting in 2021, Ram switched back to the Bosch CP3 fuel pump on 6.7 Cummins engines after issues with the CP4.2 pump used in earlier years (2019–2020). The CP3 is known for its durability and consistent fuel delivery, making it a solid choice even for stock trucks. Whether you’ve got the stock CP3 or the older CP4.2, upgrading to a quality lift pump can boost reliability and support more power.

The factory fuel system on the 6.7 Cummins includes the underbed fuel tank, fuel or lift pump, high-pressure CP3 or CP4.2 injection pump (depending on model year), and electronically controlled injectors. Ram trucks have a history of lift pump issues, especially on modified engines. Older designs mounted the pump on the driver’s side of the block behind the fuel filter. This setup absorbed heat from the engine and required the pump to “pull” fuel rather than push it, leading to failures.

Starting in 2005, Dodge moved the fuel pump into the fuel tank, which helped reduce issues. But even stock trucks can develop lift pump problems over time, especially if you’re pushing more horsepower. That’s why we recommend high-quality lift pumps from trusted brands like FASS and AirDog. These systems come as standalone pumps or integrated filtration units that remove air and debris to protect your injectors and prevent cavitation, problems the factory setup can’t handle.

In addition to lift pumps, Diesel Power Products carries a full line of performance injectors to help you get the most out of your fuel system upgrades. If you’ve added chips, programmers, or other performance mods and aren’t seeing the gains you expected, upgraded injectors can deliver the fueling your engine needs. We carry injectors from Dynomite Diesel, Industrial Injection, BD-Power, and more. You’ll also find filtration solutions to keep your fuel system clean and running right.

No matter how clean your fuel seems, contaminants and water can slip through—especially in the 6.7 Cummins fuel system. That’s why we recommend adding a good filtration system or diesel fuel additives made to keep your Ram Cummins at its best. Diesel Power Products offers additives and filtration kits to remove water and debris, protecting your injectors and pumps and keeping them running strong. These upgrades are essential for getting the most out of your 6.7 Cummins.

As always, if you are unsure of which products are right for you, do not hesitate to give us a call and we would be more than happy to help!
