John Deere Final Fuel Filter - RE544394

Key Features

• Final stage filtration (~2 µm) captures fine particulates not removed by the primary filter, protecting the high‑pressure injection system before fuel reaches injectors.
• High‑efficiency filter media traps microscopic contaminants to shield fuel injectors and high‑pressure pumps.
• Water‑repelling coated media helps separate and remove water contamination, reducing corrosion and microbial growth in the fuel path.
• Durable OEM construction meets John Deere original equipment standards for dependable performance and long service life.
• Maintains fuel flow under load thanks to optimized media and housing design that support consistent fuel delivery during demanding operation.
• Synergistic with the primary filter—works in conjunction to provide comprehensive fuel protection.
• Ideal for routine diesel fuel system servicing, safeguarding high‑pressure injectors and fuel pumps in harsh operating environments.
