The Firman T04073 tri-fuel generator is a 5000-watt, 120/240-volt trifecta with the ability to run on gasoline, propane, and natural gas with an electric starting system. It includes a 5.5-foot LPG hose for convenience using larger tanks. Its 5-gallon tank runs for 12 hours at a low 67 dB. Our Max Pro Series 223 cc engine runs cool and efficient thanks to its Phoenix fat head block. With a built-in 9-inch wheel kit and folding handle, the tri-fuel T04073 can go anywhere and perform however you like. Includes a free cover, L5-30P to TT-30R adapter and an L14-30P. Everything you need to get started is in the box including oil, funnel, operator's manual, quick start/stop Guide, and spark plug wrench.
