Fuelab: Pioneers of Digital Fuel Delivery
Fuelab, founded in 2005 and headquartered in Collinsville, Illinois, has spent two decades redefining what performance fuel delivery can be. Where conventional fuel system design relied on fixed-speed motors and cumbersome external controllers, Fuelab took a different approach — building fuel system components around digital, brushless motor technology that places precision, efficiency, and durability at the core of every product they make.
The Prodigy Legacy: Brushless Technology That Changed the Game
At the heart of the Fuelab lineup is the celebrated Prodigy series, widely recognized as the automotive aftermarket's first speed-controllable DC brushless fuel pump platform. Unlike traditional brush-style motors that wear over time, the Prodigy's brushless design eliminates that failure point entirely — delivering improved long-term durability and a dramatically lower current draw. Each Prodigy pump is hand-built, tested, and certified at Fuelab's Collinsville facility before it ships.
Fuelab's fuel pumps and electric fuel pumps are engineered around a carbon 9-vane positive displacement design with a pressure-balanced rotor and neodymium rare earth magnets for rapid response to shifts in speed and flow demand. The lineup spans an impressive range of applications — from street-friendly builds all the way to platforms rated at 2,500 horsepower — and is fully compatible with gasoline, diesel, E85, methanol, and ethanol. Billet aluminum construction with an anodized finish keeps weight low while standing up to harsh under-hood environments.
A Complete Fuel System Ecosystem
Fuelab's engineering philosophy extends well beyond the pump itself. Their fuel injection pressure regulators are precision instruments available in bypass, blocking, and electronically controlled configurations, making them equally at home on a weekend track car or a dedicated race build. To keep engines running clean, Fuelab's fuel filters feature male AN / 37° flared fitting end caps for direct integration with other fuel system components, with micron options suited to carbureted, EFI, and direct injection applications.
Rounding out the ecosystem, Fuelab's in-line check valves are high-flow, one-way units designed to prevent backflow and maintain system pressure integrity — an often-overlooked but critical element in any serious performance fuel system. Together, these components give builders a fully cohesive fuel delivery solution from a single trusted manufacturer.
Built to Race, Backed for Life
From drift to road racing, off-road to diesel performance, the street to the strip, Fuelab products are trusted by champions across motorsport disciplines. Every Fuelab-branded product is backed by a "Forever Fixed" Limited Lifetime Warranty for the original purchaser — a commitment that underscores the brand's confidence in its own engineering. Whether you are pushing a build past 1,000 horsepower or simply upgrading a daily driver's fuel system, Fuelab brings the same standard of performance, reliability, and consistency to every product in its catalog.
