The upside down pedal turn would also be zero g or low negative g (actually wouldn't that be high, since it is negative). And it never lasts for very long, since you can not have negative pitch.
In the 105 the feeder tank that can be one or two compartment is located under the passenger cabin floor.
Booster pumps are mounted on the tank floor.
Seems to me that the standard system would be prone to sucking air if the aircraft enterred zero G.
I recollect that minimum pitch on the 105 is 4 degrees 15 min. Interesting effects if you rig it to less!!!!
