The Earls Vapor Guard(TM) product line has been expanded to include O.E. fuel line quick connect fittings. These adapter fittings allow an easy way to re-use existing OEM fuel rails, fuel filters, and other components when doing an engines swap, or upgrading to Vapor Guard(TM) (or other AN Plumbing). Each fitting has a -6 AN Male Flare, and a metal retainer nut for a secure leak-free connection to the 5/16 or 3/8 SAE style fuel tube. Constructed from 6061 T6 aluminum w/ black anodized finish.

Earls Performance Products was founded by Earl Fouts in 1955 in Lawndale, California. Starting out as a small Army Navy Hardware Surplus Store serving the hot rod and racing communities of Southern California. The mission was to supply high-quality military aircraft specification 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 to the racing market and pioneered the Earls range of hoses and fittings that are still used (and copied) today. In doing so he created the racing aftermarket A.N. plumbing industry. Earls developed and patented the self-indexing adjustable hose end in 1973, known as the Swivel Seal. It allows 360 degree adjustment after installation making plumbing a snap. Earls has invented most of the special purpose racing adapters, and was the first to introduce flexible Stainless Steel PTFE lined hoses to the racing industry in the 1960s long before todays modern fuels forced many hose companies into obsoleting their hoses in search of a better solution. Earls racing heritage is second to none and is also the most replicated but never duplicated A.N. plumbing in the world. All of todays plumbing companies continue to follow Earls lead and steal from its engineering designs. Often replicated but never duplicated Earls continues to innovate plumbing for all segments of motorsports and car builders worldwide. Earls is sold across the globe and Earls has the most complete line of performance plumbing on the market. Manufacturing is headquartered in Bowling Green, KY and has four secondary distribution locations in Indianapolis on Gasoline Alley, Earls UK at the track at Silverstone, Earls Australia located in Sydney, and Earls Store 1 in Lawndale California. Earls Racing Products will continue its leadership role as the best engineered and best quality plumbing products on the market.
