Du-Bro Fuel Tanks are designed to be tough! The fuel tanks will not split or crack from vibration or pressure. In fact, the fuel tanks can be used with pressurized fuel systems! Comes complete with all hardware, including a one piece clunk with fuel barbs built right on the clunk stem. Your fuel tubing will not slide off! Du-Bro Fuel Tanks can be used with either glow-fuel or gasoline if you purchase our catalog L-DB400 Gasoline Conversion Stopper.
