Holley has announced that HP and Dominator fuel pumps and components have been approved for use with gasoline, diesel, and now E85.
They should be able to pump any of those go-juices for quite a long time too; the entire pump family has passed the 1,000-hour heated E85 testing cycle to insure their durability. Matching HP and Dominator fuel pressure regulators use a diaphragm material compatible with gasoline, diesel, alcohol and E85. The O-rings in the filters are Viton and are safe for use with all the fuels above as well.
