Fuel Cartridge
Mack

Diesel fuel filtration is essential to protect the high pressure fuel system and fuel injectors in harsh trucking environments. This cartridge removes particulates and water from the fuel stream, guarding against injector wear, fuel varnish, and clogging that can compromise power and throttle response. The robust cartridge is engineered for reliable operation under wide temperature swings and varying fuel quality, helping maintain steady fuel flow and consistent engine power. It integrates with standard fuel filters for straightforward servicing and features durable seals to minimize leaks during maintenance or engine start up. Regular replacement reduces maintenance costs by preventing premature wear in pumps and injectors, and supports smoother cold starts and better fuel economy under load. Designed with rugged Mack applications in mind, it stands up to dusty roads and highway miles alike. Courtesy of Source One Parts Center.
