I’ve got an early gen TalonSS probably 14/15 years old that I’m trying to fill. Previously have only ever used hand pump. But today I got a Venturi tank to fill my newly acquired FX. So I thought I would finally be done hand pumping my Talon, wrong. First time trying to use fill adapter that came with the rifle (pictured below). Opening bleed valve on fill tank just bled down the rifle tank completely, as if the TopHat was stuck open. Do I need a different adapter or another bleed valve somehow at the talon tank?
