Glacier Diesel Power Universal Inline Fleetguard FS1212 20-Micron Fuel / Water Separator Kit (FS1212-UK)
Description
Clean fuel starts before it ever reaches your injection pump. Dirt, rust, scale, and water can all enter a diesel fuel system through transfer tanks, bulk storage tanks, slip tanks, or even during routine fueling.
The Glacier Diesel Power Universal Inline FS1212 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 fuel filter on a Cummins-powered Dodge Ram, building a custom lift-pump system, or protecting equipment fueled from bulk storage, this kit offers dependable first-stage filtration.
Built around the genuine Fleetguard FS1212 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 FS1212 provides 20-micron particulate filtration, integrated water separation, and a drain port for removing accumulated water during routine maintenance.
Designed for flexibility and easy serviceability, this universal kit is equally at home on diesel pickups, agricultural equipment, generators, fleet vehicles, and mobile fueling systems.
Features
- Universal inline diesel fuel/water separator kit
- Genuine Fleetguard FS1212 fuel/water separator
- 20-micron particulate filtration
- Integrated fuel/water separation
- Built-in drain for water removal
- Glacier universal mounting bracket
- Choice of 3/8-inch or 1/2-inch Push-Lok fittings
- Complete mounting hardware included
- Replaceable spin-on filter
- Excellent primary filter for custom diesel fuel systems
- Ideal for transfer tanks, slip tanks, generators, farm tanks, and bulk fuel storage
Why Install a Fuel / Water Separator?
Water and larger contaminants should be removed before fuel reaches your lift pump or final fuel filter.
The FS1212 is designed as a primary-stage filter that captures larger debris while separating free water from diesel fuel. Removing contamination early helps reduce the load placed on finer secondary filters and protects expensive downstream fuel-system components.
Common sources of contamination include:
- Condensation inside fuel tanks
- Contaminated fuel deliveries
- Rust and scale
- Dirt entering through vents or filler caps
- Transfer and storage tanks
- Fuel handling equipment
Using a dedicated fuel/water separator helps create a cleaner, more reliable fuel supply before the fuel reaches the remainder of the system.
Glacier Fuel System Tech Tip
A quality diesel fuel system typically uses staged filtration.
A common layout is:
- Fuel tank
- FS1212 primary fuel/water separator
- Lift pump
- Secondary fuel filter (such as the Fleetguard FF5320 or FF5814)
- Injection pump
Using a coarse primary separator allows larger contaminants and water to be removed first, helping extend the service life of the finer secondary filter while improving overall system protection.
Why Glacier Built It This Way
Glacier designed this kit to be simple, durable, and adaptable.
The universal mounting bracket allows the separator to be installed in a convenient service location while remaining protected from road debris. Customers can select either 3/8-inch or 1/2-inch Push-Lok fittings to match their existing fuel plumbing without unnecessary adapters.
The Fleetguard FS1212 combines three important functions into one serviceable assembly:
- Primary particulate filtration
- Water separation
- Drainable water collection
The result is a universal filtration system that's easy to install, easy to maintain, and compatible with a wide variety of diesel applications.
Universal Applications
The Glacier Universal FS1212 Kit is ideal for:
- Custom Cummins fuel systems
- Dodge Ram fuel-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
Because this is a universal kit, compatibility depends on hose size, available mounting space, operating pressure, and fuel-system design.
Kit Contents
The Glacier Diesel Power Universal FS1212 Fuel / Water Separator Kit includes:
- Genuine Fleetguard FS1212 fuel/water separator
- Glacier universal mounting bracket
- Mounting hardware
- Installation hardware
- Choice of 3/8-inch or 1/2-inch Push-Lok fittings
Fuel hose, shutoff valves, lift pumps, pressure gauges, and additional adapters are sold separately unless otherwise specified.
Important Notes
- Universal installation kit.
- Designed for diesel fuel systems.
- Verify fuel-flow direction before installation.
- Confirm the selected fittings match your fuel hose size.
- Mount the separator where it is protected from road debris.
- Leave adequate clearance for future filter replacement.
- Drain accumulated water regularly.
- Prime the fuel system after installation.
- Inspect all connections for leaks before placing the system into service.
- Replace the separator according to service interval, fuel quality, or restriction.
Common Failure Point
Many fuel-system problems begin long before fuel reaches the engine.
Water, rust, dirt, and debris from storage tanks or transfer equipment can quickly reduce filter life and place unnecessary strain on the remainder of the fuel system.
Regularly draining accumulated water and replacing the separator at the recommended interval helps maintain proper fuel flow while protecting downstream filters, lift pumps, and injection components.
If excessive contamination or water is found repeatedly, inspect the fuel source, storage tank, and transfer equipment rather than simply replacing the filter.
