Before you go to pull the injectors.. Spray a dab of pb blaster etc at each o-ring. Turn the injectors before pulling the rail. These two items will help free them up if the rings are old and stuck. Pull the clips off the rail at the injector as well. Put the clips back on before the new injectors. The new injectors will snap in and hold.
Personally, I like to remove the fuel lines from the rail (takes special tool) because the plastic lines can be brittle and man handling them can crimp or cause pinholes.
Lube the o-rings with vasoline (sure it sounds funny, it's cheap and usually common).
I am familiar with the fuel line removal tool, but not sure where to pick one up? (made a cheap version once and it worked but don't want to go that route again).
thanks for the pointers on the injector removal. Will be sure to use them.
