Du-Bro fuel tanks were designed with toughness in mind! Our fuel tanks will not split or crack from vibration or pressure. In fact, our fuel tanks can be used with pressurized fuel systems! Du-Bro fuel tanks come complete with all of the hardware including our 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 glofuel or gasoline if you purchase our Cat. No. 400 Gasoline Conversion Stopper. Next time you build a model, choose a Du-Bro fuel tank.
