Glacier Diesel Power 1998.5–2002 Dodge Ram 5.9L Cummins Heated MK-7 High Flow Fuel Filter System & 3/8" Big Line Kit (MK79852-BLKH)
Description
If you want maximum fuel flow, superior filtration, and dependable cold-weather performance for your VP44-powered Cummins, the Glacier Diesel Power Heated MK-7 High Flow Fuel Filter System delivers all three.
Designed specifically for 1998.5–2002 Dodge Ram 5.9L Cummins trucks, the Heated MK-7 replaces the factory fuel filter canister with a high-flow Fleetguard FS19596 fuel/water separator, upgrades the restrictive factory supply line with Glacier's proven 3/8-inch Big Line Kit, and adds a plug-and-play heated filter base for reliable operation in cold climates.
The result is a complete fuel system upgrade that improves filtration, increases fuel flow to the VP44 injection pump, simplifies routine maintenance, and helps prevent fuel waxing during cold-weather operation—all while maintaining a clean, factory-style installation.

Why Upgrade to the Heated MK-7?
The factory fuel filter housing on 24-valve Cummins trucks is known for leaking seals, aging components, and restrictive fuel flow. Add freezing temperatures to the equation, and fuel waxing can further reduce fuel delivery when you need it most.
The Heated MK-7 solves these problems by:
- Replacing the factory filter housing with a high-flow Fleetguard spin-on filter.
- Upgrading the restrictive factory fuel line with Glacier's 3/8-inch Big Line Kit.
- Adding a plug-and-play heated filter base to help maintain fuel flow during cold-weather operation.
Whether you're towing, commuting, or running a high-performance VP44 setup, the Heated MK-7 delivers cleaner fuel, greater fuel volume, and dependable winter performance.
Glacier Fuel System Tech Tip
The Fleetguard FS19596 was designed for demanding Cummins applications and offers an excellent balance of filtration, water separation, and fuel flow.
Filter specifications include:
- 7-micron absolute filtration
- 5-micron second-pass filtration
- 98.7% filtration efficiency
- 95% free and emulsified water separation
- Approximately 90 GPH flow capacity
- Less than 1 PSI pressure differential at rated flow
The heated filter base helps reduce the possibility of fuel waxing during cold-weather operation while Glacier's 3/8-inch Big Line Kit minimizes restriction between the filter and VP44 injection pump.
Why Glacier Built It This Way
Rather than simply replacing the factory canister, Glacier engineered the Heated MK-7 as a complete fuel delivery upgrade.
The durable spin-on Fleetguard filter provides superior serviceability, while the Big Line Kit removes one of the most restrictive sections of the factory fuel system. The integrated heated filter base plugs directly into the factory wiring for simple installation, and the updated WIF sensor and connector maintain factory water-in-fuel warning functionality.
The result is improved filtration, improved fuel delivery, easier maintenance, and dependable cold-weather performance in one complete package.

Common Failure Point
The factory filter housing on VP44-equipped trucks is prone to leaking seals, difficult servicing, and restrictive fuel delivery. In colder climates, diesel fuel can also begin to wax, further reducing flow to the injection pump.
The Heated MK-7 addresses these concerns by combining a high-flow Fleetguard filter, Glacier's 3/8-inch Big Line Kit, and an integrated heated filter base into one complete system. While no filtration system can compensate for a failing lift pump, maintaining proper fuel pressure and clean, warm fuel is one of the best ways to maximize VP44 reliability.
