Also a week ago I changed the Value check O-ring on my MK3 from the factory A90 to a 006 V75 Viton and the pump became easier to pump on the down stroke !

It might not last as long because it’s softer but it’s pretty easy to change if it goes bad.
This is the one I use to replace the Main pressure O-ring, the Green one.
