I use a Mr Funnel to filter my auto fuel when I'm transferring to a Flo-Fast container then use a Flo-Fast pump to pump (http://www.flofast.com/pumpstore.html
) it into my -12. I don't care for the extra transfer that takes but does have the advantage of filtering all fuel that goes into the plane. Using the pump easily transfers the fuel into the plane.
