Yes the A pump is like a p pump(it has no keyway) I just can't figure out why someone would have done this. Also when I line up the timing marks the pump timing pin is off. I can't lock the pump. I am thinking someone has advanced the timing quite a bit. The cpl tag says it should be 14* btdc. I don't have the tool to check the timing of a A Pump.
B series cummins pump timing.
