Black Aluminum 5/16" (8mm) Hose Barb to 6AN Male Adapter

Brand: Aeromotive Fuel Systems

Finally, an easy way to add AN hose to your car's fuel system! This barbed adapter has a standard 6AN male fitting (9/16-18, 37° flare) at one end to accept any standard 6AN female hose end. The other end has a barb that is sized specifically to accept common 5/16" or 8mm ID rubber fuel hose.

The 3/4" hex is large enough for use with a crush washer on a flat-faced 9/16-18 or -6 ORB port with no internal flare.* Black anodized aluminum, made in USA. Sold individually.

* You can improve flow in this type of installation by grinding off the 37° flare.
