Glacier Diesel Power Fuel Boss Hyper Drive Upgrade | 2003–2007 Dodge Ram 5.9L Cummins (HD-03007)
Description
Increase the output of your existing Fuel Boss mechanical lift pump with the Glacier Diesel Power Hyper Drive Upgrade for 2003–2007 Dodge Ram 5.9L Cummins trucks.
Designed specifically for third-generation Dodge Ram trucks already equipped with a Glacier Diesel Power Fuel Boss system, the Hyper Drive upgrade changes the pump drive ratio to increase Fuel Boss pump speed and output by approximately 20% across the operating range.
The kit includes a high-strength 20-tooth polycarbonate pump pulley and a matching fiberglass-reinforced drive belt. These components replace the standard Fuel Boss pump pulley and belt while retaining the existing mechanical pump, mounting bracket, crank pulley, and fuel system plumbing.
This upgrade is intended for Fuel Boss-equipped trucks that require additional fuel delivery due to larger injectors, aggressive tuning, increased engine output, heavy competition use, or other applications where the standard-drive system is approaching its required fuel-delivery capacity.

What Does the Hyper Drive Upgrade Do?
The Fuel Boss is driven mechanically from the engine through a pulley-and-belt system. The relationship between the crankshaft pulley and the pump pulley determines how quickly the mechanical pump rotates in relation to engine speed.
The Hyper Drive uses a smaller 20-tooth pump pulley and matching belt to increase pump speed. Because a positive-displacement gear pump moves fuel in proportion to its rotational speed, increasing pump RPM also increases available fuel volume.
The result is approximately 20% more Fuel Boss output throughout the engine's operating range.
The Hyper Drive does not convert the system into a constant-speed pump. Fuel delivery continues to follow engine RPM:
- Lower pump speed at idle
- Increased pump speed as engine RPM rises
- Additional fuel delivery during acceleration and heavy load
- Greater available output at higher engine speeds
This preserves one of the central advantages of the Fuel Boss system: fuel delivery that naturally responds to engine demand.
Why Would a Truck Need More Fuel Boss Output?
The standard Fuel Boss drive system is appropriate for many stock, towing, and modified applications. However, the amount of fuel an engine requires can increase significantly as the fuel system and engine combination are modified.
The Hyper Drive upgrade may be appropriate for trucks equipped with:
- Larger injectors
- Aggressive performance tuning
- Increased injection duration
- High-flow injection pump modifications
- Large turbocharger combinations
- Competition-oriented fueling
- High-horsepower street builds
- Fuel systems showing pressure loss under sustained load
The purpose of the upgrade is not to create unnecessary pressure. Its purpose is to increase the mechanical pump's available output so the system can better support increased fuel demand.
Glacier Tech Tip
A higher-output drive should not be used as a substitute for proper fuel-system diagnosis.
Before installing the Hyper Drive upgrade, verify that any observed fuel-pressure loss is not being caused by:
- A restricted fuel filter
- A restricted tank pickup
- Collapsing or undersized supply hose
- Air entering the suction side of the system
- Incorrect plumbing
- A damaged check valve
- Belt slippage
- Pulley misalignment
- An improperly adjusted pressure regulator
- Excessive restriction through fittings or adapters
Increasing pump speed may provide additional supply capacity, but it cannot correct a blocked filter, air leak, poor belt alignment, or restricted pickup assembly.
Standard Drive vs. Hyper Drive
Standard Fuel Boss Drive
The standard drive configuration is designed to provide dependable fuel delivery while operating the mechanical pump at a conservative speed. It is a strong choice for stock trucks, towing applications, daily drivers, and many moderately modified engines.
Hyper Drive
The Hyper Drive changes the pump pulley and belt combination to rotate the Fuel Boss pump approximately 20% faster. This produces approximately 20% more pump output across the operating range.
The correct choice should be based on the truck's actual fuel demand—not simply on horsepower claims or the assumption that more pump speed is always better.
Why the Pulley Ratio Matters
A mechanical gear pump moves a predictable amount of fuel with each revolution. Changing the drive ratio changes the number of pump revolutions produced at a given engine speed.
With the Hyper Drive installed:
- The crankshaft continues driving the Fuel Boss belt.
- The smaller pump pulley rotates more times for each crankshaft revolution.
- The Fuel Boss pump turns faster.
- The pump moves more fuel during the same period.
- Available output increases as engine RPM rises.
This allows Glacier to increase system capacity without replacing the complete pump or adding electronic controls.
What Is Included?
The Hyper Drive upgrade includes:
- High-strength 20-tooth polycarbonate Fuel Boss pump pulley
- Matching fiberglass-reinforced Fuel Boss drive belt
This is an upgrade for an existing Fuel Boss system. It does not include:
- Fuel Boss mechanical pump
- Pump mounting bracket
- Crankshaft drive pulley
- Fuel filters
- Fuel hose
- Fuel pressure regulator
- Tank pickup
- Fittings
- Complete Fuel Boss installation hardware
Applications and Fitment

The truck must already be equipped with the applicable Glacier Diesel Power Fuel Boss mechanical lift pump system.
Important Compatibility Warning
Glacier Diesel Power Fuel Boss replacement belts and Hyper Drive components are not compatible with RASP or MITUSA fuel pump systems.
This kit should only be used with the correct Glacier Diesel Power Fuel Boss drive assembly. Similar-looking mechanical pump systems may use different pulley dimensions, tooth profiles, belt lengths, alignment, or drive geometry.
Installation Notes
Before installing the Hyper Drive upgrade:
- Confirm that the truck has the correct Fuel Boss system.
- Inspect the pump shaft and pulley mounting area.
- Inspect the crankshaft drive pulley.
- Verify that both pulleys are properly aligned.
- Confirm that the belt path is free from interference.
- Follow the specified belt-tension procedure.
- Rotate the engine or drive assembly by hand where practical to verify alignment.
- Recheck belt tracking after installation.
- Inspect the system after the first operating cycle.
Excessive belt tension can place unnecessary load on the pump and drive components. Insufficient tension can allow slippage, belt wear, reduced pump speed, and inconsistent fuel delivery.
Fuel System Tech Tip
Fuel pressure should always be evaluated under the conditions where the problem occurs.
A truck may show acceptable pressure at idle while experiencing a pressure drop during:
- Wide-open throttle
- Sustained towing grades
- Higher engine RPM
- Heavy fueling commands
- Competition use
When diagnosing system capacity, use a properly installed fuel-pressure gauge and observe pressure under load. This provides more useful information than an idle-only pressure reading.
The goal is not simply to achieve the highest possible pressure. The goal is to maintain the pressure and volume required by the injection system throughout the truck's actual operating range.
Common Installation and Diagnostic Problems
Belt Misalignment
If the pump and crank pulleys are not operating in the same plane, the belt may walk toward one edge, wear unevenly, or leave the pulley.
Incorrect Belt Tension
A loose belt can slip and reduce pump output. An overtightened belt may accelerate wear on the pump or drive components.
Restricted Fuel Supply
A high-output pump cannot perform correctly if the tank pickup, filter, supply hose, or fittings restrict fuel before it reaches the pump.
Air Intrusion
Loose fittings or damaged hose on the suction side may allow air into the system without producing an obvious external fuel leak.
Incorrect Application
This pulley and belt combination is designed specifically for the applicable third-generation Fuel Boss system. It is not a universal mechanical lift-pump upgrade.
Is the Hyper Drive Right for Your Truck?
The Hyper Drive is most appropriate when:
- The truck already has a compatible Fuel Boss system.
- The engine's fuel demand exceeds or approaches standard-drive capacity.
- Fuel pressure has been tested under load.
- Filters, plumbing, tank pickup, and drive alignment have been verified.
- Additional pump output is actually required.
The standard-drive arrangement may remain the better choice for a stock or mildly modified truck that already maintains proper fuel pressure.
