Reliable engine performance starts with clean fuel. The FS1000 (also known as FS 1000) is a critical fuel water separator designed to protect high-pressure common rail systems from water contamination and microscopic debris. Whether you are operating a Cummins marine engine or a Komatsu excavator, using an OEM-standard filter is the most cost-effective way to prevent expensive fuel injector failures.
As a professional heavy-duty engine parts supplier, we provide Brand New FS1000 filter elements that meet or exceed original specifications for filtration efficiency and moisture removal.

1. Why is the engine losing power and showing "Low Fuel Pressure" codes?
This is often caused by a restricted FS1000 filter. When the filter captures excessive contaminants or water, the fuel flow is restricted. Replacing the FS1000 promptly prevents cavitation in the fuel injection pump.
2. How often should I drain the water from the FS1000 separator?
For high-duty cycles on Komatsu PC300 excavators, water should be drained daily via the bottom valve. The entire FS1000 unit should be replaced every 500 hours or during every oil change.
3. Why Choose This Fuel Water Separator?
Our FS1000 utilizes an OEM-standard tri-metal structure for the base plate and premium media. It is trusted by repair shops & equipment fleets worldwide for maintaining fuel purity in harsh environments.
