656 simple simple simple tractor. the line is bad cracked the 656 didn't have and seal rings on them the used a swedge type seal basicly the high pressure line had a lil machined end on it that is tightened against the fitting on the pump. take it off take it to a CaseIH dealler tell them model tractor year and which cylindar it is. Bleeding is simple you should have on the supply line from the tank a lil hand primer pump and on top of the filters lil bleed screws start with the first filter open bleed screw pump til solid fuel (no air bubbles) close screw open second bleed screw pump til solid fuel close loosen supply line to pump pump til solid fuel. never pre fill filters always bleed with hand primper because you run a great risk of introducing foreign material i.e. dirt into the fuel pump and fuel pumps hate dirt and air bubbles so if you take care of the fuel system youll have a long and trouble free life.
