http://flyunleaded.com/Aviation_Fuel_Update_6_2012.pdf (45 page .PDF). See slide 30 especially. The EAA link on slide 30 is a 404 though. It should be:
http://www.eaa.org/en/eaa/aviation-communities-and-interests/pilot-resources/auto-fuel-stc/approved-engine-models
Looks like you might need to spend < $300 for a Supplementary Type Certificate (STC).
HTH a bit.
Good luck!
Cheers,
