Fleetguard FS19855 Fuel Filter & Water Separator | 2000–2002 Dodge Ram 5.9L Cummins
Description
The VP44 injection pump used on the 2000–2002 5.9L Cummins depends on two things for a long service life: clean fuel and a consistent fuel supply.
Every gallon of diesel flowing through your truck can contain microscopic dirt, rust, water, or other contaminants. Left unchecked, these contaminants can wear internal fuel system components, reduce injector performance, and contribute to premature wear throughout the fuel system.
The Fleetguard FS19855 Fuel Filter & Water Separator is a genuine OEM replacement for 2000–2002 Dodge Ram 2500 and 3500 trucks equipped with the 5.9L 24-Valve Cummins. Featuring Fleetguard's StrataPore® synthetic filtration media, the FS19855 provides 10-micron filtration with excellent water separation while maintaining the fuel flow your VP44 fuel system requires. It supersedes the discontinued Fleetguard FS19579 and installs directly into the factory filter housing.
Whether your truck is stock, modified, used for towing, or driven daily, routine fuel filter maintenance is one of the best investments you can make in the reliability of your diesel fuel system.

- Replaces discontinued Fleetguard FS19579
Why Fuel Filtration Matters
Unlike the later common rail engines, the 2000–2002 Cummins uses a Bosch VP44 electronically controlled injection pump.
While the VP44 is extremely capable, it's also sensitive to contaminated fuel and poor fuel supply. Dirt, rust, water, and other debris can gradually wear precision-machined components throughout the fuel system.
Replacing your fuel filter at the recommended interval helps protect:
- VP44 injection pump
- Fuel injectors
- Fuel passages
- Overflow valve
- Fuel transfer components
Clean fuel is one of the simplest ways to help keep your truck running reliably.
Glacier Tech Tip
Many owners focus on the VP44 itself but overlook the condition of the fuel entering it.
A neglected fuel filter gradually becomes more restrictive as it traps contaminants. Excessive restriction can reduce the amount of clean fuel available to the injection pump, especially under heavy load.
Replacing the fuel filter on schedule—and ensuring the lift pump is supplying proper fuel pressure—are two of the most important maintenance items on any VP44-equipped Cummins.

Important Notes
- Genuine Fleetguard FS19855 fuel filter and water separator.
- Direct replacement for the factory filter.
- Features advanced StrataPore® synthetic filtration media.
- Includes a replacement sealing O-ring.
- Always lubricate the O-ring before installation.
- Prime the fuel system according to factory procedures after replacing the filter.
- Replace at the recommended service interval or sooner if poor-quality or contaminated fuel is suspected.
Common Failure Point
Many fuel system problems begin long before any symptoms appear.
Microscopic contaminants and water gradually wear precision components inside the fuel system, while an overdue filter can become increasingly restrictive. Both conditions can reduce overall fuel system reliability over time.
Routine fuel filter replacement helps maintain clean fuel delivery, supports proper fuel flow, and protects expensive fuel system components from unnecessary wear.
