From page 45... ...
Initial ethanol use in a geographic region has been reported to cause batches of off-specification gasoline and plugged automobile fuel filters, as well as occasional damage to fuel injectors. To avoid potential problems with water, most refiners do not transport ethanol-gasoline blends by pipeline.

From page 46... ...
In general, companies consider it to be impractical to meet summer vapor pressure specifications below about 7.6 psi with 10 percent ethanol blends. The vapor pressure of ethanol blends can be reduced by using special coblending agents, such as higher alcohols, or by blending to higher ethanol concentrations.
