Replacing Fuel Injection Pump O-Ring
It looks like I need to replace the O-Ring between the injection pump and the crankcase, i noticed that it is leaking oil (not fuel) and I am trying to fix the few remaining leaks.
I remember reading somewhere that I could replace this O-Ring without having to completely remove the whole injection pump...is this true and if so is there anything I need to pay attention to? Thanks!

You may be confused with the individual fuel delivery o rings on the top of the pump,however I regret to advise that if you want to install the shaft o ring in one piece---the pump comes out and if you do that I would put the o ring back on a reconditioned pump.
If you do not have access to WIS and all the special tools required to correctly do the job, I would let it leak until the car dies or you are forced to give it up in a divorce action!!
