I have one last pump set up for sale but the pump again has no knob. I have the dble drilled bungs and canes with elbows. The only thing youll need is some standard 5/16" racking hose to run from racking cane to racking cane. You can easily make a knob for this pump out of a pce of wood. It is easily operational as is though. Ill let all this go for $140 shipped in the US.
