Since their debut in the early 1990s, Walbro 255LPH intank fuel pumps have been the industry standard by which all other 255LPH fuel pumps are judged. Walbrosfirst design was a center-inlet 190LPH pump for the Mustang 5.0 and Buick GrandNational. Later, Walbro added more inlet configurations and increased volume to255LPH, allowing their pumps to be installed into just about every modernvehicle on the road today. Thebenefit of today's return-style fuel systems is that any unused fuel isautomatically returned to the tank via the return line, which makes Walbrointank pumps suitable for turbocharged, supercharged, as well as stock replacementapplications. These fuel pumps can safely support 500hp, or 600hp+ whenused in conjunction with ourhotwirekit.All Walbro fuel pumps are Made in the USA.
