Check with your local fire marshal about requirements for using UL-approved ethanol pumps.
Nearly all tanks and lines are approved by Underwriters Laboratories (UL) for use with E85. Steel tanks are approved, but some older fiberglass tanks may not be. Check with the manufacturer or at BYOethanol.com to be certain.
Originally, blender pumps – and all E85 pumps, for that matter – were installed using standard gasoline pumps. According to UL, no complaints have been filed and no failures have been noted in installations using standard pumps to dispense E85 and other mid-level blends.
Specifically, the E85 FAQ section of UL’s website says the group has “no documented reports of field failures or safety issues associated with UL listed or recognized components used with E85.”
In August of 2010, Underwriters Laboratories (UL) approved several blender dispensers manufactured by Dresser Wayne and Gilbarco for use with E85 and mid-level ethanol blends. Some cities, counties, and states require that only UL-listed pumps be used to dispense fuel, and those jurisdictions have prevented retailers from marketing E85 since UL withdrew an earlier approval in October of 2006. Most jurisdictions have made exceptions for E85 and blender pumps in the past, and some don’t use UL as the standard. It’s a good idea to check with your local fire marshal to determine what the regulations are in your area.
