It's normal to have some air especially on low pump speeds.
Okay i will add grease to the o ring and not worry about it. I will post a photo or video of the pump and return. I know for all you experts this easy, but doing this for the first time and getting a lot of misinformation from other sources with no practical hands on makes it easy to freak out, lol.
Thanks again for helping, being ocd, i promise i will be a pro at this soon and will help others.
