Fuel Filter
Mack

The Fuel Filter is designed to protect engine fuel systems by removing particulates and contaminants before they reach high-precision injectors and pumps. Its filtration media and housing are chosen to withstand diesel chemistry and high-pressure fuel lines common in heavy-duty trucks. A clean filter reduces injector wear, helps maintain optimal fuel pressure, and minimizes the risk of clogged passages that can cause misfires or rough running. The filter is engineered for straightforward, tool-assisted replacement, which keeps downtime to a minimum during routine maintenance. It also helps stabilize engine performance across the operating envelope, from cold starts to high-load conditions, by delivering cleaner fuel to the combustion chamber. Regular replacement ensures consistent fuel flow and protection for critical fuel system components. Source One Parts Center.
