Default Re: Injector Leak-off Test

I realise they have an O ring which makes the seal but is it necessary to use pliers or some other tool in order to get them out. What are the chances of breaking plastic fittings that have been sitting on top of a hot engine for over 200K miles? Hell you would think changing a fuel filter would be a simple task too....................................
Once the clips are removed the fitting should pop straight off.

You are correct to be concerned about breaking the fairly fragile plastic fittings. As I recall I was able to get the side of a flat screwdriver blade under the fittings to pry up on it a bit. Be certain to keep the blade in close on the fitting body and go from one side to the other as the fitting begins to rise. Perhaps using 2 blades at once.

Be careful and good luck.
