MOPAR 68436631AA Fuel FIlter (2019-2024 Ram HD 6.7 Diesel/2020-2023 Ram 3.0 Diesel)

With any common rail diesel engine, such as your Cummins, it is imperative to replace your fuel water separator at the normal service intervals. If gone untouched, water will bypass into your injectors, causing increased wear on not only the injectors, but poor combustion which can lead to reduced fuel mileage and power. This is a direct, factory replacement for a simple, hassle-free maintenance. Works with 6.7L and 3.0L engines.
