Glacier Diesel Power Universal Inline Heated Fleetguard FS1001 10-Micron Fuel / Water Separator Kit (FS1001-UK-HT)
Description
Cold weather and water contamination are two of the most common threats to diesel fuel-system reliability. The Glacier Diesel Power Universal Inline Heated FS1001 Fuel / Water Separator Kit is designed to address both by combining primary fuel filtration, water separation, and automatic cold-weather protection into one universal package.
Built around the genuine Fleetguard FS1001 fuel/water separator, this kit is ideal for custom diesel fuel systems, frame-mounted factory-filter bypass installations, transfer tanks, farm tanks, generators, and industrial equipment. It combines 10-micron particulate filtration with integrated water separation and a self-regulating heated filter base that helps reduce cold-weather fuel restriction where it commonly occurs—inside the filter itself.
The heated base automatically regulates itself based on temperature and requires only a keyed 12-volt power source. There are no switches or external controllers to operate. The kit also includes Glacier's universal mounting bracket, installation hardware, your choice of 3/8-inch or 1/2-inch Push-Lok fittings, and 10-foot power leads protected by split loom. Longer power leads are available upon request.
Whether you're protecting a daily-driven diesel truck, a fleet vehicle, or equipment operating in harsh winter conditions, this kit provides an excellent first stage of filtration before fuel reaches your lift pump and secondary fuel filter.

Why Install a Heated Fuel / Water Separator?
Many diesel owners focus on fuel filtration but overlook water contamination and cold-weather operation.
The FS1001 is designed to address both.
As temperatures fall, paraffin wax naturally found in diesel fuel begins forming crystals. Those crystals often accumulate inside the first filter in the system, restricting fuel flow long before the fuel itself has completely gelled.
At the same time, water contamination can reduce fuel lubricity, promote corrosion, damage injection components, and encourage microbial growth inside tanks.
The heated FS1001 helps by:
- Separating free water from diesel fuel
- Capturing larger particulate contamination
- Applying heat directly to the separator during cold-weather operation
- Helping reduce wax accumulation within the filter
- Protecting downstream lift pumps and secondary filters
For many diesel fuel systems, this serves as the ideal primary filtration stage.
Glacier Fuel System Tech Tip
Every premium diesel fuel system should perform three separate jobs before fuel reaches the injection pump:
- Remove water
- Remove larger contaminants
- Remove fine particulate contamination
The heated FS1001 performs the first two functions while helping improve cold-weather fuel flow.
A properly staged fuel system typically follows this layout:
- Fuel tank
- Heated FS1001 Fuel / Water Separator
- Lift pump
- FF5814 NanoNet final fuel filter
- Injection pump
This arrangement allows the separator to remove water and larger debris while the finer secondary filter performs the final polishing before fuel reaches the injection system.
The exact layout should always follow the lift-pump manufacturer's recommendations regarding filter placement and operating pressure.
Why Glacier Built It This Way
Rather than heating the fuel tank or requiring complicated external controls, Glacier focuses heat where cold-weather restriction commonly begins—the filter element.
The self-regulating heated base automatically adjusts operation according to temperature and requires only a keyed electrical source. Once installed, no switches or manual adjustments are needed during normal operation.
The universal frame bracket provides a durable mounting solution while allowing easy access for routine maintenance, draining accumulated water, and replacing the separator.
Customers can select either 3/8-inch or 1/2-inch Push-Lok fittings to match their existing fuel plumbing without unnecessary adapters or restrictions.
The result is a straightforward system that combines:
- Primary fuel filtration
- Water separation
- Automatic cold-weather heating
- Easy serviceability
- Universal installation flexibility
Why Water Separation Matters
A standard fuel filter primarily removes dirt.
A fuel/water separator performs two separate jobs:
- Removes particulate contamination
- Separates free water before it reaches sensitive fuel-system components
Water contamination can contribute to:
- Corrosion inside injection pumps
- Injector damage
- Reduced fuel lubricity
- Rust inside storage tanks
- Microbial growth
- Frozen fuel-system components during winter
- Premature filter restriction
Removing water before it reaches the remainder of the fuel system helps improve long-term reliability and reduces unnecessary wear.
Cold Climate Benefits
The heated separator is especially valuable for equipment that:
- Operates below freezing
- Sits outdoors overnight
- Uses transfer tanks during winter
- Works in remote locations
- Cannot tolerate unexpected fuel restrictions
- Experiences frequent cold starts
While the heated base helps maintain fuel flow through the separator, operators should still use winter-blended diesel fuel whenever available and follow recommended anti-gel practices for their region.
The heater is intended to complement proper winter fuel management—not replace it.
Universal Applications
This kit is well suited for:
- Custom Cummins fuel systems
- Dodge Ram frame-mounted fuel filter conversions
- Custom lift-pump installations
- Diesel pickup trucks
- Agricultural equipment
- Construction equipment
- Oilfield trucks
- Diesel generators
- Transfer tanks
- Slip tanks
- Bulk diesel storage systems
- Fleet fueling trailers
- Industrial diesel equipment
Compatibility depends on the fuel-system configuration, operating pressure, hose size, expected fuel flow, available mounting space, and electrical system.
Kit Contents
The Glacier Diesel Power Universal Heated FS1001 Kit includes:
- Fleetguard FS1001 fuel/water separator
- Self-regulating heated filter base
- Glacier universal mounting bracket
- Mounting hardware
- Choice of 3/8-inch or 1/2-inch Push-Lok fittings
- 10-foot power leads

Applications and Fitment
This is a universal installation kit.
Installation requires:
- Compatible diesel fuel system
- Suitable mounting location
- Correct fuel-flow orientation
- Matching hose size
- A keyed 12-volt power source
- Adequate clearance for future servicing
Some drilling, fabrication, wiring, plumbing, or additional application-specific fittings may be required.
Important Notes
- Universal installation kit.
- Designed for diesel fuel systems.
- Heater requires a keyed 12-volt power source.
- Use an appropriately fused electrical circuit.
- Verify fuel-flow direction before installation.
- Confirm the selected fittings match your hose size.
- Mount the separator where it is protected from road debris.
- Keep wiring and fuel hoses away from exhaust heat and moving components.
- Leave enough clearance below the filter for servicing.
- Drain accumulated water regularly.
- Prime the fuel system after installation.
- Inspect all fuel and electrical connections before placing the system into service.
- Continue using winter diesel fuel and approved anti-gel additives when required by operating conditions.
Common Failure Point
Many cold-weather fuel problems begin with a partially restricted separator rather than a failed lift pump.
As wax crystals and contamination accumulate, restriction across the separator gradually increases. If water is also allowed to remain inside the separator, both cold-weather performance and filtration efficiency may decline.
Possible symptoms include:
- Hard starting
- Low fuel pressure
- Hesitation under load
- Lift-pump noise
- Reduced power
- Water contamination
- Frequent filter plugging
- Cold-weather stalling
Regularly draining accumulated water and replacing the separator at recommended intervals helps maintain proper fuel flow and system protection.
If the separator repeatedly accumulates excessive water or becomes restricted, inspect the fuel source, storage tank, transfer equipment, tank vents, and fuel handling practices rather than simply replacing the filter.
