There are about 170,000 filling stations in the United States right now, but according to the Renewable Fuels Association only about 1,100 of those were selling E85 at the beginning of 2007. This poses a problem for the owners of the six million flex-fuel cars and trucks that have been put on the road since 1998 and the million more that are expected to be added this year. The RFA expects the number of E85 pumps to climb to somewhere between 1,500 and 2,000 by the end of this year and really take off in 2008. One of the main stumbling blocks has been Underwriters labs. In many locations fire codes require fuel pumping equipment to be UL Certified. UL recently finished their testing and is expected to start certifying new equipment later this year.
