I will use auto fuel. I thought this was straight forward, but I have found out by now (thanks in large part to this board ) that this is not as straight forward as I thought. For instance, Ellison TBI cannot be used due to chemical incompatibility between auto fuel and materials used in the TBI.
More in general terms I also got the understanding that AN fittings not neccesarily are compatible with autofuel. I have no idea if this is "just the specs", ie they are only spec'ed for AVGAS but there are no physical or chemical incompatibilities with auto fuel, or they are only spec'ed for AVGAS because there really are chemical incompatibilities, like the Ellison. I also wonder if there are any difference bewteen fittings vs AVGAS and Jet fuel.
Maybe it is better to use automitive fittings?
