Founded in Michigan in 1950 by Walter E. Walpole, Walbro began as a specialist in small‑engine carburetors and evolved into a global leader in engine management and fuel systems. With manufacturing in the U.S., Mexico, Japan, China, Thailand, and Italy—headquartered now in Tucson, Arizona—it produces carburetors, EFI systems, ignition modules, fuel tanks, and fuel pumps.

Around 2014, its automotive fuel pump business was acquired by TI Automotive (now TI Fluid Systems), yet their pumps—achieving 255–525 LPH—continue to be manufactured in Michigan under the Walbro/TI Automotive brand. These include award-winning dual-channel and E85-capable models like the GSS341, GSS342, TIA485, and Hellcat series, designed for builds up to 900+ hp.

Widely used in automotive, marine, powersports, and small-engine markets, Walbro/TI pumps are renowned for reliability, high flow, and OEM-grade quality. Their enduring legacy and modern innovation make them a top choice for performance and OEM-level fuel delivery systems.
