Fuelab 10303 Velocity 100 In-Line High Performance Diesel Lift Pump

The Fuelab 10303 Velocity 100 is a high-performance in-line lift pump engineered specifically for the diesel performance market. Delivering 100 GPH (gallons per hour) at 8 PSI with an internal bypass, this pump-only unit is designed to supply clean, consistent fuel to your injection pump with minimal noise and maximum reliability.

At its core, the Velocity 100 uses a DC brushless motor paired with a high-efficiency sling vane positive displacement pump. The brushless motor design eliminates brushes that can wear out or corrode, while the wet motor design removes the need for dynamic shaft seals — two of the most common failure points in conventional fuel pumps. The result is a durable, long-service-life lift pump capable of supporting demanding diesel performance builds.

Key Features:

• 100 GPH flow rate with internal bypass at 8 PSI
• High-efficiency sling vane positive displacement pump design
• Special housing shape engineered for extremely quiet operation and steady pressure
• Carbon 9-vane construction with pressure-balanced rotor for high reliability
• Lightweight, super-efficient DC brushless motor reduces current draw
• Low-mass rotor for rapid response to changes in speed and flow demand
• Powerful high-flux density Neodymium rare earth magnets
• Wet motor design — no dynamic shaft seals that can wear out
• No motor brushes to corrode or wear (low-sulfur diesel compatible)
• 12–24V vehicle electrical system compatibility
• Billet aluminum construction with MIL-A-8625 Type II anodizing
• Multi-fuel compatible Fluorosilicone static seals
• Accepts standard or port-style -10AN fittings

The 10303 is sold as a pump only unit, giving builders the flexibility to integrate it into a custom diesel fuel system. For a complete setup, Fuelab offers compatible filter kits, vortex air separators, and installation kits (sold separately). Backed by Fuelab's Forever Fixed lifetime warranty covering defects in materials and workmanship.
