I'm not sure this is official but I believe the fuel scoop works by grabbing hydrogen out of the Corona of stars in SC.
If this were to be the case, why can't we fuel scoop from Wolf Rayyet, T-Tauri or Herbig stars?
Wolf Rayyets actually are characteristic for their incredibly strong solar wind so if anything they should give you more fuel. T-Tauris definetly don't have much solar wind as they are still in the process of compression although that doesn't mean they don't eject gas and either way, they have a protoplanetary disk from which you could also fuel scoop, Herbigs are just very massive T-Tauris so the logic goes the same way.
