It is commonly used in Chevrolet/GMC trucks (1992-2002) and Hummer (1993-2004) models equipped with the 6.5 L turbo diesel or naturally aspirated diesel engines. It serves as a direct fit into the factory fuel filter base system.
The filter is built using an enhanced cellulose media designed for durability and efficient filtration. It has a nominal micron rating of 14 µm. The construction includes corrosion-resistant components, with top and bottom rigid elements.

This fuel filter offers real-world performance advantages—removing contaminants that can lead to injector wear, maintaining fuel system health, and extending engine lifespan. It meets OEM standards and provides a reliable solution for road, off-road, agricultural, and heavy-duty applications where the 6.5 L diesel is used. It is sold individually and is intended to replace factory filters directly.
