Max-Motorsports..we are a family-owned and operated small business since 2000 in the USA. Don't get "hosed" by the competition. Customize your ride and update your worn out carburetor vent hoses with our Max-Flo Carburetor Vent lines available in over 15 colors. All of our hoses are made in the USA. Our 4mm ID hoses are the same ID as factory hose and were designed to fit snugly and securely. All of our 3 Hose kits are cut to factory lengths to eliminate guess work. All kits include 3 cable ties and a sticker. Some carburetor bottom float bowl drains use a smaller (1/8") 3.2mm hose while others use the standard 4mm ID hose - please choose the correct size when ordering. The shade of the 3.2mm ID bowl drains will be slightly different due to the smaller size of the hose. Heat (away from all fuel sources) and pliers will assist with installation. Hose clamps and Carburetor are not included.
