E-Fuel’s Microfueler is a portable unit which resembles a portable gas (petrol) pump. It features an LCD touch screen interface and a retractable pumping hose that extends to 50 feet (about 17 metres), allowing the user to situate the pump in a convenient location at home without needing to place it directly beside a vehicle.

E-Fuel co-founder Floyd Butterfield is a scientist who has been working on an at-home ethanol brewing kit for many years. In 2006 he conceived the design for the MicroFueler and in March 2007 Quinn signed on to create the company.
