If that's the case, why do my Milodon pumps ALWAYS prime themselves? I don't do anything with the lines.
Please explain it to me because I really want to know?
Maybe it's karma

but really, I've been using Milodon oiling systems since the early 70s..almost 40years. If you can give me a reason why I went from having those problems..to not having any, please give me a reason that makes sense.
