I think I'm going to do an Airflow Performance FM-200.  The reason is because it's the larger fuel system that uses a purge valve.  The FM-200A does not, and may struggle with hot restarts.  Another option is the EFII, but it requires return to tank fuel line, a duplex valve, and it's nearly $8000.

Yes, it would be selector valve -> inline filter -> electric aux pump -> through firewal -> to engine driven fuel pump -> to fuel control unit -> outlet of fuel control (metered fuel) to fuel flow transducer -> to inlet of purge valve flow divider assy.

The purge return is teed into one of the fuel tank feed lines before the selector valve.  Since you have a high wing plane we have a fitting for your selector valve that has provisions for the return and installation of a check valve so that the purge return line can be removed without draining the fuel tank.

Yes the system is compatible with auto gas. Understand the vapor pressure of auto gas is higher than avgas therefore there may be operational issues with higher ambient temperatures. Also varnish build up is a concern with storage and repeated evaporation In the components.
