Description
The FASS XWS5000 1-12 Inch Transfer Tank Filter is an Extreme Water Separator engineered by FASS Fuel Systems to protect diesel-powered trucks, SUVs, and equipment from the damage caused by contaminated fuel. Unlike a standard gas filter or gas pump filter designed for occasional use, this transfer tank fuel filter and water separator is built for the demanding job of filtering fuel as it moves from a bulk storage tank or fuel transfer tank into the tank of your truck, tractor, or other diesel equipment. If you’ve ever asked what is a fuel filter and why it matters, the answer is simple: it’s the last line of defense between dirty, water-laden fuel and the sensitive components of your fuel system, injectors, and engine.
Overview
Every gallon of diesel that sits in a transfer tank or storage tank is exposed to condensation, rust, dirt, and particulate buildup over time. The FASS XWS5000 addresses this head-on as a dedicated fuel filter and water separator, rated at 10 microns to capture fine contaminants before they ever reach your equipment’s fuel pump filter or injection system. It has been field tested and laboratory proven to remove over 99 percent of water from diesel fuel, giving you confidence that what’s going into your tank is clean, dry fuel — not a slow drip of System-damaging moisture and grit.
Key Benefits
Unlike many inline fuel filters that rely on a manual drain to separate water, the FASS XWS5000 uses advanced filter media that positively traps water within the filter itself, eliminating the need for a drain valve. This makes it a low-maintenance, set-and-forget solution for anyone who regularly transfers fuel from a storage tank. With a flow rate of up to 25 gallons per minute, it keeps fueling fast and efficient, making it well suited for high-volume truck fuel filter applications where waiting around isn’t an option.
Thread Size & Compatibility
Built with a 1 inch-12 thread, the XWS5000 is designed to integrate into existing transfer tank and fuel pump filter setups without requiring specialty adapters. Whether you’re upgrading your current setup or building a fuel filter replacement kit for your fuel transfer system, this filter installs into applications feeding Truck/SUV fuel systems, making it a practical fuel fuel filter upgrade for anyone serious about protecting their diesel investment.
Fitment
The FASS XWS5000 is intended for Truck/SUV applications and is sold as each. It’s built specifically as a transfer tank filter rather than a direct in-line vehicle fuel filter, so it’s ideal for the storage or transfer tank stage of your fueling process — the point where fuel fuel filter and water separator protection matters most before that fuel ever reaches your fuel pump and filter downstream.
