## Description

**This kit is for most full-size MX carbs using 3 Hoses. Please see our 4mm/3.2mm ID 10'ft Carb Vent Hose kits for 5-6 hose carbs** 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 10 colors. This kit is for full-size carburetors requiring 3 vent hoses. Our 4mm ID hoses are the same ID as factory hose and were designed to fit snugly and securely. All of our 5'ft kits are uncut and will require cutting to custom lengths. All kits include 3 cable ties and a sticker. Some carburetor float bowl drains use a smaller (1/8") 3.2mm hose. This smaller ID hose (if needed) is also included. Heat (away from all fuel sources) and pliers will assist with installation. Hose clamps and carburetor are not included.

Review: Great product - Works perfect fix the problem we were having,great price, durable, super flexible and great size
Review: Worked for Keihin 38 - Overall this tubing worked for my keihin 38 carb, the lines are a little small for the two larger vent ports, but alittle grease helped with install. Only complaint is I wish it was a 6' length of tubing vs 5'. Mine are all even, about 1" below the swing arm.
