The pumps are easily repaired/rebuilt. A local automotive electrical shop can do this for you. It's usually just brushes and a cleanup of the poles on the armature. Sometimes they get wet and the insides need work- the fields may need to be replaced. Rebuilds are usually alot cheaper than replacements.

Definitely do them both.

Right fluid???
Maybe to thick for it to pump?

My understanding is straight 30weight non detergent oil
is what I was told on my new Tab

Depends on the pump. Older one's took hydraulic fluid.

I started a thread on hydraulic fluids a few months back. There are lots of "answers", but the best philosophy seems to be "put in what the sticker on the pump says".
