In the world of heavy-duty machinery, engine protection is non-negotiable. If you are operating equipment powered by Isuzu 4HK1 or 6HK1 engines, ensuring clean fuel delivery is the first step toward avoiding costly downtime. Our premium fuel water separator, specifically identified by part numbers 8-98013986-1 and 8980139861 (Hitachi cross-reference 4676385), is engineered to meet or exceed OEM standards for moisture removal and particulate filtration.
Heavy excavators like the Hitachi ZX200-3, ZX210-3, and ZX240-3 rely on high-pressure common rail systems. Contaminated fuel can lead to catastrophic injector failure. This assembly ensures that water is effectively separated before it reaches the fuel pump, protecting your investment from internal corrosion and power loss.
