Glacier Diesel Power | Fuel Boss Replacement Mechanical Pump

Glacier Diesel Power FB-1000 Fuel Boss Replacement Mechanical Lift Pump | Genuine Replacement Pump

Description

Keep your Fuel Boss system operating like new with a genuine Glacier Diesel Power FB-1000 Replacement Mechanical Lift Pump.

The FB-1000 is the same heavy-duty gear-driven pump used in Glacier Diesel Power Fuel Boss systems. Designed to replace only the pump—not the complete assembly—it allows you to restore your existing Fuel Boss system without replacing brackets, pulleys, filters, or plumbing.

Unlike conventional electric lift pumps that rely on motors, brushes, bearings, and electronics, the FB-1000 is a mechanical external gear pump driven directly by the engine through the Fuel Boss belt drive. As engine RPM increases, pump output increases proportionally, supplying additional fuel volume exactly when the engine demands it.

The FB-1000 utilizes precision straight-cut steel gears, a 100% Viton® shaft seal, and a rugged pump housing engineered to withstand the harsh operating conditions found in diesel trucks. When installed with proper belt tension and routine maintenance, the FB-1000 is designed for exceptional service life.

Whether you're rebuilding a high-mileage Fuel Boss system or simply keeping a spare pump on the shelf, the genuine Glacier Diesel Power replacement pump delivers the same reliability your original system was built around.

Why a Mechanical Lift Pump?

Most aftermarket lift pumps rely on an electric motor that runs at a constant speed regardless of engine load.

The Fuel Boss system takes a different approach.

Because the FB-1000 is mechanically driven by the engine, fuel delivery naturally follows engine demand.

At idle, the pump provides excellent fuel pressure without excessive flow.

As RPM increases under towing or acceleration, pump speed and fuel volume increase automatically, helping maintain consistent fuel pressure throughout the operating range.

This simple mechanical design eliminates many of the failure points commonly associated with electric lift pumps, including:

• Electric motors
• Brushes
• Armatures
• Electronic controllers
• Electrical connectors
• Motor overheating

Glacier Tech Tip

One feature that makes the FB-1000 unique is its operating speed.

The Standard Drive Fuel Boss system turns the pump at a 2:1 reduction ratio, meaning the pump spins at only half engine speed. At normal highway cruise, the FB-1000 is operating at roughly 25% of its maximum rated RPM, greatly reducing wear while still delivering more than enough fuel for nearly every street, towing, and performance application. For customers with higher fuel demand, Glacier also offers the Hyper Drive pulley system, which increases pump speed and fuel output by approximately 20% over the standard drive ratio.

Why Choose the Genuine FB-1000?

The Fuel Boss system was engineered around this exact pump.

Every genuine FB-1000 features:

• Precision-machined internal gear set
• Heavy-duty pump housing
• Viton® shaft seal for modern diesel fuels
• Proven compatibility with ULSD and biodiesel
• Direct bolt-in replacement
• Designed specifically for Fuel Boss systems

Using the original Glacier Diesel Power pump ensures your existing brackets, pulleys, belts, and plumbing continue to operate exactly as designed.

Common Failure Point

While the FB-1000 is engineered for exceptional longevity, like any mechanical component it should be inspected whenever the Fuel Boss drive system is serviced.

Signs that the pump may require replacement include:

• External fuel leakage from the shaft seal
• Reduced fuel pressure after confirming belt tension and filter condition
• Excessive internal wear after very high mileage
• Physical damage from debris or improper installation

Before replacing the pump, always inspect the belt, pulleys, filters, plumbing, and fittings. Many fuel delivery issues are caused by worn belts or restricted filters rather than the pump itself.
