Walbro: A Legacy of Fuel System Innovation

Walbro has been engineering fuel system solutions since its founding in November 1950 by Walter E. Walpole in Fenton, Michigan. Over the decades, the company evolved from a small-engine carburetor specialist into a global leader in engine management and fuel delivery technology. Today, Walbro serves the Outdoor Power Equipment, Recreational, Marine, and Personal Transportation markets with a comprehensive product lineup that spans carburetors, ignition systems, fuel tanks, valves, and of course, fuel pumps.

Headquartered in Tucson, Arizona, and operating ISO-certified manufacturing and engineering facilities in the United States, Japan, Mexico, Thailand, and China, Walbro brings true global manufacturing scale to every product it produces. With over 2,300 employees worldwide, the company has the infrastructure to support both original equipment manufacturers and the performance aftermarket with equal precision.

Fuel Pumps Built for Real-World Demands

When it comes to fuel pumps, Walbro has earned a reputation that few brands can match. The iconic GSS-series pumps — including the widely recognized Walbro 255 — became the go-to choice for performance enthusiasts and professional tuners alike, capable of supporting 500 horsepower and beyond under standard operating conditions. These pumps are engineered to deliver consistent fuel flow at high pressure, making them equally effective in daily drivers and dedicated race builds.

Walbro’s electric fuel pumps represent the cutting edge of in-tank and inline fuel delivery. Available in flow ratings from 255 LPH all the way up to 535 LPH, these pumps cover applications ranging from mild street builds to all-out forced-induction builds demanding E85/flex-fuel compatibility. The dual-channel turbine designs found in top-tier Walbro electric pumps are the same award-winning OEM technology found in some of the world’s most powerful production vehicles.

Walbro’s roots in small-engine technology mean its mechanical fuel pumps are equally well-developed, serving the power equipment, marine, and recreational vehicle markets where reliable, pulse-driven fuel delivery is essential. Whether the application calls for a rotary gerotor-type pump or a traditional diaphragm design, Walbro’s mechanical pump portfolio reflects decades of engineering refinement.
