EE 338 Fuel Filter

EE-338 High-Efficiency Fuel Filter / Water Separator (Replaces R120T)

Protect your engine's fuel system with the EE-338 Fuel Filter, a high-performance replacement for the industry-standard Racor R120T. Designed for modern diesel engines, this filter serves as a critical line of defense, separating damaging water and solid contaminants from your fuel before they reach the injectors.

With its 10-micron filtration rating, the EE-338 strikes the perfect balance between high-flow capacity and superior protection, making it ideal for both marine and heavy-duty industrial applications.

Key Performance Features:

• Aquabloc® Technology Equivalent: Engineered with water-repelling media that causes water to coalesce into large droplets, which safely settle in the collection bowl.1

• 10-Micron Precision: Captures microscopic particles to prevent injector wear and fuel system corrosion.

• Spin-On Convenience: Features a 1"-14 thread for easy installation and a high-quality seal to prevent air leaks in suction-side applications.

• Durable Steel Canister: Built to withstand the high-pressure and high-vibration environments of commercial diesel engines.
