"Earl's Quick Connects adapt popular GM, Ford and Chrysler 3/8" male fuel connections to -6 AN hose ends. They utilize dual O-ring seals, factory-style steel internal snap retainer, and an external stainless steel redundant clip to deliver the ultimate in safety. These adapters allow a -6 hose end to be mated to factory fuel rails and fuel tank male line connectors. The O-ring material was developed specifically for the factory quick connects and was optimized to resist today's fuels like E85 and new fuel additives that damage common O-rings.

About Earl's Performance

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.
