Ensure 100% free water removal with the Cat® 326-1643 Advanced High Efficiency Fuel Water Separator. Engineered for 336E, 349D excavators and C15 engines, this carbon steel filter group protects high-precision injectors from moisture and fine contaminants. Buy original-quality filtration to reduce downtime and maintenance costs. Global shipping available.
The 326‑1643 Fuel Water Separator is a critical primary‑stage fuel‑system component for Caterpillar high‑pressure common‑rail engines. It removes 100 % free water, 90 % emulsified water and fine abrasive contaminants from fuel. By blocking moisture and impurities at the primary stage, it protects high‑precision fuel injectors, avoids internal corrosion and power loss, and extends the service life of secondary filters.

AHE Advanced‑Efficiency Media: Special filter‑paper structure intercepts ultra‑fine particles and micro water droplets that ordinary filters cannot capture, ensuring ultra‑clean fuel supply.
Multi‑Stage Protection System: Primary‑stage separation reduces the load on secondary filters, greatly lowering the risk of damage to high‑cost precision injectors.
Vibration‑Resistant Heavy‑Duty Housing: High‑strength carbon steel shell resists extreme vibration and pressure fluctuations in mining and heavy‑construction environments.
Fleet‑Operation Optimization: Stable fuel quality avoids water‑induced engine failures and downtime, improving overall fleet operational efficiency and profitability.
