3rd Gen 6.7L Cummins Fuel System

Ensure clean fuel delivery, protect your high-pressure common rail components, and maximize fuel flow on your 2007.5–2009 3rd Gen 6.7L Cummins with heavy-duty fuel system upgrades. Factory lift pumps and filtration setups are notoriously prone to failing under the high demands of modified or heavily towed 6.7L diesels, leaving expensive injectors vulnerable to contamination and starvation. Upgrading to a high-capacity Fass/AirDog lift pump, advanced filtration kits, and upgraded lines ensures consistent fuel pressure, eliminates air entrapment, and delivers bulletproof reliability under extreme-duty use.
