The award winning 5 Gallon SureCan is perfect for those bigger machines. With innovative flow control and rotating pouring spout technology， SureCan offers its user the best experience they have ever had with a gas can! The flexible spout rotates down more than 180 degrees and fits perfectly into any machines fill location while the thumb release trigger on top controls the flow. By pulling straight back on the safety trigger and then down on the thumb button fuel is released immediately while you stay in complete control the entire time. When you notice your fill tank is almost full slowly release the thumb button and allow the excess fuel to drain from the top of the spout before rotating it back up. No more bending over and tipping your fuel can forward and holding it in an awkward position!
