This is the same top quality Fuel Hose that we use in our carburetor kits. It features an inner woven nylon sleeve to increase the pressure rating and provide a pliable, long life, easy-to-install fuel line. 30R6 Fuel Hose slips easily over Dellorto or Weber fuel lines and requires only slight clamping pressure to form a leak proof seal. 30R6 Fuel Hose is available in 5-foot lengths and measures 1/4" I.D.
