Thanks for the Answers... I've got a white one, and he has no Leak... Maybe the Reflux Valve in the Pump is broken...becouse when I press down the pump, and I let them down, the air remains in the air tank ... but if I let go of the pump, it pulls the air back, out of the tank... I think I must buy a new Pump...

Hi everybody Two Days ago I bought the "Lego pneumatik Airtank". But he don't works...! he doesn't fill... Can anyone help me? Thanks Mike
