EE 334 Fuel Water Separator Filter

EE-334 Heavy-Duty Fuel Water Separator (Replaces 3903410)

Protect your diesel engine’s fuel system from the leading cause of downtime: water and particle contamination.1 The EE-334 Fuel Filter is a premium spin-on fuel-water separator designed to replace the Cummins/AGCO 3903410.

By stripping moisture and micro-particulates out of your fuel before they reach the injectors, the EE-334 prevents corrosion, injector clogging, and power loss. It is an essential component for high-pressure common rail (HPCR) systems and traditional diesel engines alike.

Key Performance Features:

• Superior Water Separation: Advanced media effectively separates emulsified water from diesel fuel.

• High Efficiency Filtration: Rated for high particle removal (approx. 13 microns at 99% efficiency) to protect sensitive fuel components.

• Rugged Shell Design: Built with a heavy-gauge steel canister to withstand the high vibration and pressure of industrial environments.

• Easy Installation: Precision-machined 13/16-18 threads ensure a leak-free, hand-tightened seal.

Verified Compatibility & Cross-Reference

The EE-334 is a direct replacement for the 3903410 and is interchangeable with the most trusted names in heavy-duty filtration.
