    Earls AT991966ERL Details

    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. The Earl's redundant clips secure the connection at six points by metal retainers. Virtually every other competitive quick connect uses plastic clips with only two points of retention. Although quick connects with plastic clips are sometimes used for vent and factory fuel tank connections, they are not typically used near the engine where high temperatures are present. The Earl's external safety clip is retained with a chain to keep the clip from being misplaced when disconnected. This chain can easily be removed and replaced with safety wire if preferred. These quick connects can be detached with the same tool that you used to remove the factory fuel line and is an inexpensive purchase at any auto parts store. Don't settle for second best when it comes to your fuel connectors. Choose Earl's!

    • Adapts popular GM, Ford and Chrysler factory 3/8 male fuel connections to -6 & -8 AN
    • Utilizes reliable factory-style metal internal and external redundant retainers which assures connection will not snap loose as seen with plastic versions
    • O-ring material developed specifically for the same application on factory vehicles to tolerate today™s fuel additives and E85
    • One hand click connection to factory fuel rails and lines
    • Chain tether keeps external clip close when detached or can be replaced with safety wire for an additional layer of security
    • Legendary Earl™s quality built-in

    We use only the best products on all of our clients ride. Now day everyone has gone to the modern power plants and with the late model fuel systems thes fitting make it so much nicer to build a custom fuel line system than using the poor engineered factory lines!
