Review: OK - OK
Review: Rebuilding required - How do I get a rebuild kit for this pump. As my previous review said, I tried it with oil after it was received. It worked fine. The first time I actually needed it (6 weeks after purchase) it doesn’t work at all. It’s blowing oil out of the exhaust. I purchased it in May, it didn’t work the weekend before July 4th. Again, how do I get a rebuild kit because my return window had expired. Please help!! I have no way to contact CNCest?
