Overview

What It Does & How It Helps

The fuel filter is the last line of defense for your injection system, trapping the abrasive dirt, rust and water that destroy injectors and the high-pressure pump. Diesel injectors meter fuel at extremely tight tolerances, and modern common-rail and CP4 pumps are especially sensitive to contamination and to the poor lubrication that water causes. Installing a fresh, correctly-rated filter (and draining or replacing the water separator where equipped) restores full fuel flow, protects those expensive components, and cures the hard starting, hesitation and power loss that come from a clogged or water-logged element. It is the cheapest insurance a diesel owner can buy.
