Earl's Performance Products was founded by Earl Fouts in 1955 in Lawndale, California. The mission was to supply high-quality military aircraft surplus plumbing components directly to the racing industry from a small retail outlet. As the military surplus market dried up, Earl recognized the need for continuity of supply for the racing market and pioneered the Earl's range of hoses and fittings that are still used today. In doing so he created the racing aftermarket plumbing industry.
