In diesel engine systems, a fuel filter water separator is a critical component that protects your engine from harmful contaminants and water in the fuel. For generator sets ranging from 10kW up to 3000kW, the right choice of water separator—such as the 500FG, 900FG, or 1000FG series—is essential to ensure engine reliability, reduce maintenance costs, and extend equipment lifespan.

At Fleeyoude, we specialize in manufacturing premium diesel fuel filter water separators designed to meet the stringent requirements of modern diesel engines in generator sets, marine engines, and heavy machinery worldwide.

What Is a Diesel Fuel Filter Water Separator?

A diesel fuel filter water separator is a combined filtration device installed in the fuel line to perform two essential tasks:

  • Filter out solid particles and contaminants such as rust, dirt, and debris from diesel fuel.

  • Separate and remove water that may be present in the fuel system, preventing water-induced engine damage.

Water in diesel fuel can cause injector corrosion, reduced combustion efficiency, and serious engine damage. Therefore, effective water separation is vital to protect your diesel engine’s fuel injection system.

Fleeyoude’s 500FG / 900FG / 1000FG Fuel Filter Water Separators Overview

Our product lineup includes the widely used 500FG, 900FG, and 1000FG series, which are compatible with various diesel generator sets ranging from small to large power outputs.

How Fleeyoude’s Water Separators Protect Your Generator Sets

Our diesel fuel filter water separators use a three-stage filtration process:

  1. Cyclonic action separates larger water droplets and particles.

  2. Coalescing filters combine smaller water droplets into larger ones.

  3. High-efficiency filter elements remove fine particles and residual water for clean, dry fuel.

This design protects fuel injection systems, reduces engine wear, and prevents downtime caused by fuel contamination.

Application Scenarios

  • Small generators (10kW–100kW): Use Fleeyoude’s 500FG single-unit separators for compact, reliable protection.

  • Mid-size generators (100kW–500kW): Dual-unit models with selector valves (e.g., 75500FGX) allow filter changes without shutting down equipment.

  • Large industrial generators (500kW–3000kW): High-flow 1000FG separators meet the heavy-duty demands of large power plants and marine engines.

How to Choose the Right Water Separator?

  • Confirm your generator set’s power rating and fuel flow requirements.

  • Provide your engine model and original filter part numbers if possible.

  • Choose between single or dual unit designs based on your maintenance needs—dual units allow continuous operation during filter replacement.

  • Select filter micron ratings (2, 10, or 30 micron) to match fuel quality and operating environment.
