I have a pump just like this one. But I'm tired of the hand pump. I want to keep the tube but find a electric vaccum pump so I can change the hand pump. But were do I find one. Just the pump.
So recently I’ve been having some decent expansion and sessions in my larger cylinders so last week I decided to order the next two sizes up and tonight I’m going to give my 3.25 a try this going to get interesting
