Questions and answers
I would like to know witch hose goes where , like pressure side and return side
The hose that connects to the pressure side of the BLB hydraulic BM20 is the one supplying high-pressure fluid from the pump. The hose that connects to the return side, also called the tank line, carries low-pressure fluid back to the tank. The return line must be large enough to carry the flow with little pressure.
