Default Rotary Pump dumping fuel between the pump and timing case!!!!

Hey guys I have a Case skid loader with a 4bt cummins and a bosch rotary pump since its basically the same as the old first gen i figured I would diagnose the problem here.

So this morning while feeding cows the loader started running like crap so I flipped the cab and found diesel running down the side of the block like a small river!!! So we shut it down and figured it was coming from the front of the pump. So my question is there a seal up front could blow out to allow diesel to leak that bad?? or am i looking at bigger problems Thanks fellas!!! and this loader does have over 5000 hard hours on it so it doesn't owe me anything
