Glacier Diesel Power 2003–2007 Dodge Ram 5.9L Cummins MK-2+ Fuel Filter System & 3/8" Big Line Kit – Cylinder Head Mount (MK20307-CHMB)
Description
Aftermarket intake manifolds shouldn't prevent you from protecting your CP3 injection pump.
The Glacier Diesel Power MK-2+ Cylinder Head Mount System was engineered specifically for 2003–2007 Dodge Ram 5.9L Cummins trucks equipped with aftermarket intake manifolds. This unique design relocates the filter assembly using a heavy-duty cylinder head mounting bracket, allowing you to enjoy the benefits of Glacier's MK-2+ system without interference from aftermarket intake components.
The system combines a genuine Fleetguard FF5320 high-efficiency fuel filter with Glacier's proven 3/8-inch Big Line Kit, adding an additional stage of filtration before the CP3 injection pump while replacing the restrictive factory fuel supply line. The result is cleaner fuel, improved fuel flow, and increased protection for one of the most expensive components in your common rail fuel system.
Whether your truck is a daily driver, tow rig, or high-horsepower build, the MK-2+ Cylinder Head Mount delivers the fuel volume and filtration needed to support reliable performance.

Why Upgrade to the MK-2+ Cylinder Head Mount?
The factory fuel system was never designed with today's performance upgrades in mind.
When an aftermarket intake manifold is installed, many traditional secondary filter kits no longer fit correctly. Glacier solved that problem by relocating the filter with a dedicated cylinder head mounting bracket while keeping all the benefits of the MK-2+ system.
The MK-2+ improves the fuel system in two important ways:
- Adds high-efficiency secondary filtration before the CP3 injection pump.
- Replaces the restrictive factory fuel line with Glacier's high-flow 3/8-inch Big Line Kit.
This combination helps deliver cleaner fuel with less restriction, making it an excellent upgrade for everything from stock trucks to serious performance builds.
Glacier Fuel System Tech Tip
The Fleetguard FF5320 has earned its reputation by combining excellent filtration with exceptional flow.
Flowing nearly 100 GPH with less than 1 PSI of pressure drop, the FF5320 is capable of supporting virtually any horsepower level while helping protect the CP3 injection pump from fine particulate contamination. When paired with Glacier's 3/8-inch Big Line Kit, the system provides outstanding fuel delivery without creating unnecessary restriction.
Why Glacier Built It This Way
Not every truck retains the factory intake manifold, and Glacier wanted those owners to have the same level of fuel-system protection.
The cylinder head mounting bracket was engineered specifically for trucks running aftermarket intake manifolds, providing a rigid mounting location while maintaining excellent serviceability. The laser-cut, CNC-formed bracket positions the filter securely, while the included Big Line Kit improves fuel flow between the factory filter housing and the CP3.
The result is a clean installation that delivers:
- Additional CP3 protection
- Improved fuel flow
- Easy filter service
- Compatibility with aftermarket intake manifolds
- Factory-quality fit and appearance
Applications
Fits:
- 2003 Dodge Ram 2500 5.9L Cummins
- 2003 Dodge Ram 3500 5.9L Cummins
- 2004 Dodge Ram 2500 5.9L Cummins

Important: This kit is designed for trucks equipped with aftermarket intake manifolds. It is not intended for trucks equipped with an engine-mounted APPS or Jacobs Exhaust Brake. Glacier offers dedicated versions for those applications.
Kit Contents
The Glacier Diesel Power MK-2+ Cylinder Head Mount Kit includes:
- Fleetguard FF5320 fuel filter
- Cylinder head mounting bracket
- Glacier 3/8-inch Big Line Kit
- High-flow fuel hose and fittings
- Mounting hardware
- Installation components
Important Notes
- Fits 2003–2007 5.9L Common Rail Cummins.
- Designed for trucks with aftermarket intake manifolds.
- Not compatible with engine-mounted APPS or Jacobs Exhaust Brake applications.
- Uses the factory fuel filter housing with an added secondary filter.
- Prime the fuel system after installation.
- Inspect all fuel connections for leaks before operating the engine.
Common Failure Point
As horsepower and fuel demand increase, the restrictive factory fuel line and lack of secondary filtration can become limiting factors for long-term CP3 reliability.
The MK-2+ Cylinder Head Mount addresses both concerns by combining Glacier's proven Big Line Kit with an additional Fleetguard FF5320 filter, helping maintain fuel flow while providing another layer of protection for the injection pump and injectors.
