Hi All,
i have the bendix style silverhawk throttle body combined with the airflowperformance fuel pump/filter unit without a return line.
the pump/filter assembly is the old spaghetthi style setup from AFP. (the newer assembly looks much cleaner but should have the same or similar components.)
i was thinking to do an tank dry run test during cruise flight with my 7 and in preparation for that i came across a warning from AFP not to do so:

it states that an air lock "will" be formed at the outlet of the boost pump making the lycoming silent. what do you think?
for me that implies that you should never unport the fuel pick ups in the tanks at all, not only running tanks intentionally dry during flight but also unporting situations due to slips at final, ucoordinated turns, aerobatics etc. is this setup especially problematic when it comes to that i kind of situations?
Cheers
