Walbro is an American company founded by Walter E. Walpole in 1950 specialising in fuel delivery parts. Walbro carburettors are common on leaf blowers, whipper snippers, chainsaws and garden edgers, but Walbro are most famous for their fuel pumps. The venerable Walbro 255lph in-tank fuel pump is probably the most common, reliable and proven fuel system upgrade used in the aftermarket performance automotive world today, and the 460lph pump an excellent modern equivalent.
