Hi sorry im very new to all this but i had a broken primer lever for a fluval 407 unit. I replaced the primer but theres some sort of gasket/seal inside the unit that is missing and i am struggling to find a replacement as have no idea what size it was or what its actually called, i have the o ring and the intake/outtake gasket rings but its the gasket/seal that goes in between the primer handle and the plunger in the unit. Can anyone help me
