The Alliant Power AP57006 Fuel System Contamination Kit is designed to repair diesel fuel system damage on 2013-2018 Ram 2500 and Ram 3500 trucks equipped with the 6.7L Cummins ISB engine. This complete fuel system replacement kit restores proper fuel delivery after contamination caused by DEF entering the fuel tank, debris in the fuel system, or fuel system component failure.

If your Cummins powered Ram experienced diesel fuel contamination or requires a complete fuel system refresh, replacing the affected components helps ensure proper injector performance and fuel pressure. Modern high-pressure common rail fuel systems operate with extremely tight tolerances measured in microns, making them highly sensitive to contamination.

Frequently Asked Questions

Click each question below to expand the answer.

What causes fuel contamination on a Cummins?

Fuel contamination can occur when DEF enters the diesel tank, water contaminates the fuel supply, or debris circulates through the high pressure fuel system.

Why replace the entire fuel system after contamination?

Metal debris or contaminants can remain inside injectors and rails. Replacing affected components prevents repeat failures.

Will this kit fit Ram cab and chassis trucks?

No. This kit is designed for Ram 2500 and 3500 pickup trucks only and does not fit cab and chassis models.

Why are diesel fuel systems sensitive to contamination?

Modern high pressure common rail fuel systems operate with extremely tight tolerances, meaning even microscopic debris can damage injectors and fuel system components.
