Fleetguard FS19596 Fuel & Water Separator with WIF Sensor | 7-Micron Spin-On Fuel Filter

Fleetguard FS19596 Fuel & Water Separator with WIF Sensor | 7-Micron Spin-On Fuel Filter

Description

Clean, dry fuel is essential for protecting today's diesel fuel systems.

While dirt and debris are common contaminants, water is one of the biggest threats to diesel fuel systems. Water reduces diesel fuel's lubricating properties, promotes internal corrosion, encourages microbial growth, and can accelerate wear on injectors, lift pumps, and high-pressure fuel pumps.

The Fleetguard FS19596 Fuel & Water Separator with Water-in-Fuel (WIF) Sensor is a genuine heavy-duty spin-on fuel filter engineered to remove both solid contaminants and water before they reach your engine. Featuring advanced StrataPore® synthetic media, 7-micron filtration at 98.7% efficiency, and 95% emulsified water separation, the FS19596 delivers exceptional protection while maintaining the fuel flow required by demanding diesel applications. It also serves as the replacement element for the Glacier Diesel Power MK-7 Fuel Filter Kit and is the upgraded replacement for the Fleetguard FS1003.

Whether you're maintaining a work truck, industrial engine, generator, agricultural equipment, or a Glacier fuel filtration system, clean fuel starts here.

Why Water Separation Matters

Many people think fuel filters only remove dirt.

In reality, removing water is just as important.

Water can enter diesel fuel through:

• Condensation inside the fuel tank
• Contaminated fuel storage tanks
• Poor-quality fuel
• Temperature and humidity changes
• Bulk fuel handling equipment

Once inside the fuel system, water can:

• Reduce fuel lubricity
• Cause corrosion inside injectors and pumps
• Promote biological growth in fuel tanks
• Damage precision-machined fuel system components
• Lead to expensive repairs

A quality fuel and water separator helps remove these contaminants before they ever reach your engine.

Glacier Tech Tip

Diesel fuel naturally attracts moisture over time.

Even if your truck or equipment rarely sees rain, condensation can form inside partially filled fuel tanks as temperatures fluctuate between day and night.

That's one reason many heavy-duty diesel engines utilize a dedicated water separator ahead of the engine's primary fuel filter.

The integrated Water-in-Fuel (WIF) sensor allows compatible systems to monitor water accumulation and alert the operator before excessive water reaches the engine, giving you an opportunity to service the filter before damage occurs.

Why Choose Genuine Fleetguard?

Fleetguard has been designing filtration systems for Cummins and heavy-duty diesel engines for decades.

The FS19596 is engineered to provide the ideal balance of:

• High-efficiency contaminant removal
• Excellent water separation
• Low fuel restriction
• High contaminant holding capacity
• OEM-quality sealing
• Long service life

Unlike economy replacement filters, genuine Fleetguard filters are developed to meet the demanding operating conditions found in commercial, industrial, agricultural, and performance diesel applications.

Common Applications

The Fleetguard FS19596 is commonly used in:

• Glacier Diesel Power MK-7 Fuel Filter Kits
• Heavy-duty diesel trucks
• Cummins-powered equipment
• Agricultural equipment
• Construction equipment
• Industrial diesel engines
• Generator sets
• Marine diesel applications
• Custom diesel fuel filtration systems

Replaces:

• Fleetguard FS1003
• Cummins 3954891

Important Notes

• Genuine Fleetguard FS19596 fuel and water separator.
• Features advanced StrataPore® synthetic filtration media.
• Includes provision for a Water-in-Fuel (WIF) sensor.
• Replace according to your engine or equipment manufacturer's recommended maintenance schedule.
• Lubricate the gasket with clean diesel fuel before installation.
• Properly prime the fuel system after replacing the filter.
• Drain accumulated water as required on compatible systems.

Common Failure Point

Many diesel fuel system failures begin with contamination that can't be seen.

Microscopic particles gradually wear precision fuel system components, while water contamination reduces lubrication and promotes corrosion inside pumps and injectors. Left unchecked, both can lead to expensive repairs and unnecessary downtime.

Replacing your fuel and water separator at the recommended service interval is one of the simplest and most effective ways to protect your diesel engine and maintain reliable performance.

Complete Your Fuel System

For complete fuel system protection, pair the Fleetguard FS19596 with:

• Glacier Diesel Power MK-7 Fuel Filter Kit
• Glacier Diesel Power Fuel Pressure Test Kits
