Now we may have E20

E20 is just fine for fuel pumps, says Minnesota Ag Department — Autoblog Green

The Center, which operates out of Minnesota State University, Mankato, just released a study that found an E20 blend "causes no significant change in performance of automotive fuel systems." This study, the fourth E20 project the Center has conducted, was all about the fuel pumps and sending units. Eight models of fuel pumps were run for 4,000 models on three different fuels (pure gasoline, E10 and E20).
