Rubber gasket is inside the Reservoir when you first get it. This rubber gasket is for the top.
When you first open the reservoir, and take that silly manual out and rubber gasket...you will see the bottom gasket kind of all the way inside the groove.
Note you don't need the rubber gasket for the top for vertical installations. Not that I saw.
I'll repost post#223 here since I have got many questions on this:
Got few PM's on how to install Aqualis/open on to Adaptor..So step by step here. This is my second time, so I know what I did wrong first time.
Left Aqualis, center AQ D5 Adaptor (no case, but who cares), and right AQ D5 Pump: Front right are the yellow AQ pump installs...Can I use these on vertical installs??
After package is opened, just need pump metal brace and ring, 4 M3x12 mm screws ( i think), the manual MPS G1/4 . Leave rest in bag
The aqualis manual is in the reservoir. Duh. So take glass part with top and turn counter clockwise, while holding base:
Take top G1/4 off center tube and place on left hole off adaptor (if you want to reuse). Also attach the aqualis to top part of Adaptor now. You don't want to attach with glass on, otherwise your turns with Allen key will take a long time:
Insert the ring on pump and place while flat:
Tighten till the brace for pump goes all the down.
Place the ring in the Aqualis to top part of aqualis, and press down with the glass tube:
Turn the Aqualis clockwise till its tight. Place the manual MPS pressure release on top of Aqualis in the G1/4
Trying these non-vibration AQ bolts here :
Left is with rubber pads from Aqualis and right is with separate order:
