This is our extended Spout Adapter with the length being 3" and the reduced tip diameter of 7/8". This will fit inside an Easy Fuel™ Capless Fuel Filler system and most double-flapper fuel fillers. This will screw onto all the ends of your Race, PAX, Blitz, and Coarse Thread Nozzles. It allows you to fit your nozzle into more confined spaces and prevent spills. The cap is not included.
