Earl's Swivel-Seal Banjo hose ends use 6AN hose and are a slick way to connect the hose directly to the carburetor. The revised design uses a more attractive stainless steel banjo bolt, and copper crush washers. These hose ends are now available w/black anodized finish(single banjo style-double banjo style will be release at a later date) Replacement stainless steel banjo bolts are also available separately.
