I am attempting to remove my N* engine (Head bolt problems) and find that I am stalled at the gate. The Fuel cable has a clip of some sort that holds the cable on and I can't see how to release it without damaging it. I have also encountered the same type of problem with the shift linkage. it has a plastic ball clip holding the linkage to the lever. I have tried to pry this off with on success and again am concerned about damageing it. Is there some tool or trick to these two problems

 

spray some lube, should slide forward and off
