OK, don´t laugh now:
Rad (B.I Micro), 1/4"-> 3/8" adapter, pump, WB, T-connector for filling/bleeding, 3/8" -> 1/4" adapter, back to rad. Might be some air traped in the adapter between rad and pump. might be hard for pump to suck water through adapter and/or from B.I.M.bo.
Doesn´t seem to be any more air stuck in WB.
