Hunter 40 back creek
I have a 1985 hunter with a 4JHE motor and the injection pump has three ports not allowing feel the pass-through I tried freeing up the valves while the injection pump was in the boat on the engine but I have to remove the pump anyone out there remove one of these before I know there’s a procedure so you don’t get the pump out of timing and if anybody can help me with that or a video I’ve got it ready to unbolt from the front housing thank you
