I ended up modifying a nylon spacer to fit and it seems to be a nice fit.
Now I found another bad seal, however I’m unsure of how to get this one out. Under the water pump plate is a plastic piece and a seal under that, in which I’m trying to get to. The only problem is that I do not know how to remove this piece. In the manual, it looks like it could unscrew but to no avail on that venture.
Has anyone seen this or know how to remove it?
