Glacier Diesel Power Universal Inline Fleetguard FS1001 10-Micron Fuel / Water Separator Kit (FS1001-UK)
Description
Water is one of the most damaging contaminants a diesel fuel system can encounter. Unlike particulate contamination that can often be captured by a standard fuel filter, water reduces fuel lubricity, promotes corrosion, encourages microbial growth inside fuel tanks, and can accelerate wear throughout the fuel system.
The Glacier Diesel Power Universal Inline FS1001 Fuel / Water Separator Kit provides an easy way to add primary fuel filtration and water separation to virtually any custom diesel fuel system. Whether you're bypassing the factory filter housing on a Cummins-powered Dodge Ram, building a custom lift-pump system, or protecting fuel coming from a transfer tank or bulk storage tank, this kit provides a serviceable first stage of defense against contaminated fuel.
Built around the genuine Fleetguard FS1001 fuel/water separator, the kit includes Glacier's universal frame-mount bracket, installation hardware, and your choice of 3/8-inch or 1/2-inch Push-Lok fittings.
The FS1001 combines 10-micron particulate filtration with integrated water separation and a drain port, allowing accumulated water to be removed during routine maintenance.
The result is a universal filtration package that helps protect lift pumps, injection pumps, injectors, and downstream fuel filters while making routine maintenance easier.

Why Install a Fuel / Water Separator?
Most diesel owners focus on dirt contamination, but water can be equally destructive.
Water can enter diesel fuel systems through:
- Condensation inside partially filled tanks
- Contaminated fuel deliveries
- Outdoor fuel storage
- Poorly maintained transfer tanks
- Rainwater intrusion
- Repeated temperature changes
Unlike diesel fuel, water does not provide the lubricity required by fuel-system components. Even small amounts can contribute to corrosion, injector damage, reduced lubricity, and microbial contamination inside storage tanks.
A dedicated fuel/water separator captures particulate contamination while helping separate free water from the fuel so it can be drained before reaching sensitive downstream components.
For most diesel fuel systems, a fuel/water separator is best positioned as the primary filtration stage ahead of finer secondary filtration.
Glacier Fuel System Tech Tip
Every diesel fuel system benefits from staged filtration.
Rather than asking one fine filter to perform every job, many premium fuel systems use two separate filtration stages.
Primary Stage
- Separates free water
- Captures larger particulate contamination
- Helps protect the lift pump
- Reduces contamination reaching the final filter
Secondary Stage
- Captures finer particulate contamination
- Provides final filtration before the injection system
- Helps protect the injection pump and injectors
The FS1001 is designed to serve as the primary-stage separator by removing water and larger contaminants before the fuel reaches the finer final filter.
For customers building a premium custom fuel system, pairing the FS1001 with the Fleetguard FF5814 NanoNet filter creates a complete two-stage filtration arrangement.
Why Glacier Built It This Way
A universal fuel/water separator should be simple to install, easy to service, and flexible enough to fit a wide range of diesel applications.
Glacier designed this system around a dedicated frame-mount bracket that keeps the filter securely mounted while allowing access for inspection, draining accumulated water, and replacing the filter.
Customers can choose between 3/8-inch and 1/2-inch Push-Lok fittings to match their existing fuel system rather than adapting the entire system to one hose size.
The Fleetguard FS1001 was selected because it combines three important functions into one serviceable assembly:
- Primary fuel filtration
- Water separation
- Drainable water collection
This design reduces maintenance complexity while providing an effective first stage of protection for downstream fuel-system components.
Why Water Separation Matters
A standard fuel filter primarily captures dirt and particulate contamination.
A fuel/water separator performs two separate jobs:
- Removes particulate contamination
- Separates free water from diesel fuel
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 rest of the fuel system is one of the most important steps in protecting diesel injection components.
Universal Applications
The Glacier Universal FS1001 Kit can be adapted to:
- Custom Cummins fuel systems
- Dodge Ram factory-filter bypass systems
- Custom lift-pump installations
- Diesel pickup trucks
- Agricultural equipment
- Construction equipment
- Diesel generators
- Transfer tanks
- Slip tanks
- Farm fuel storage
- Bulk diesel storage tanks
- Fleet fueling trailers
- Industrial diesel equipment
Compatibility depends on the fuel-system layout, operating pressure, available mounting space, hose size, and expected fuel-flow requirements.
Transfer Tank and Bulk Fuel Applications
Fuel quality begins long before diesel reaches the truck.
Transfer tanks and bulk storage systems may collect:
- Rust
- Dirt
- Scale
- Condensation
- Free water
- Debris introduced during fueling
Installing the FS1001 on the outlet side of a transfer system helps remove water and particulate contamination before the fuel enters the receiving vehicle or equipment.
This is especially useful for:
- Farms
- Ranches
- Construction companies
- Oilfield service trucks
- Fleet operations
- Mobile fueling trailers
The separator helps reduce contamination leaving the storage tank, but it does not replace proper tank inspection and maintenance.
Kit Contents
The Glacier Diesel Power Universal FS1001 Fuel / Water Separator Kit includes:
- Genuine Fleetguard FS1001 fuel/water separator
- Glacier universal mounting bracket
- Mounting hardware
- Required installation hardware
- Choice of 3/8-inch or 1/2-inch Push-Lok fittings
Fuel hose, shutoff valves, pressure gauges, lift pumps, and additional adapters are sold separately unless otherwise specified.
Applications and Fitment
This is a universal installation kit.
Installation requires:
- A compatible diesel fuel system
- A suitable mounting location
- Correct hose size
- Proper fuel-flow orientation
- Adequate clearance for future service
Some drilling, plumbing, fabrication, or additional fittings may be required depending on the application.
Important Notes
- This is a universal installation kit.
- Designed for diesel fuel systems.
- Verify fuel-flow direction before installation.
- Confirm the selected fittings match the hose size being used.
- Mount the assembly where it is protected from road debris and impact.
- Leave adequate clearance below the filter for servicing.
- Drain accumulated water regularly.
- Prime the fuel system after installation.
- Inspect all fuel connections for leaks before placing the system into service.
- Replace the filter according to fuel quality, restriction, and service interval.
- Repeated water accumulation may indicate contamination inside the vehicle or storage tank.
Common Failure Point
Many customers replace the fuel filter without regularly draining the accumulated water.
As water collects inside the separator, the available collection capacity is reduced. If the separator is not serviced, water may eventually continue downstream into the remainder of the fuel system.
Possible signs of water contamination may include:
- Hard starting
- Rough running
- Injector problems
- Corrosion
- Microbial contamination
- Premature filter plugging
- Reduced fuel-system reliability
Draining accumulated water during routine maintenance is just as important as replacing the filter element itself.
A separator that repeatedly fills with water should lead to an inspection of the fuel source, storage tank, vehicle tank, filler cap, venting system, and fuel handling practices.
