Hi there sorry im new to this, i repaired my partners fluval 407 filter but found that the primer leaks water from the top of the unit, looking into it further, i have misplaced a seal/gasket that is meant to be in place between the primer handle and the base plunger. Can anyone help me identify where i can get this seal/gasket from

If it's like the o-ring shown here (go to 6:19), you can buy it from eBay. Just measure the thickness of the plunger (that's the ID of the o-ring) and the diameter of the housing (that's the OD of the o-ring) to make sure you order the correct size.
