If you are going to do the work yourself, here are a couple of pointers:
1. The four fuel injector ports in the head are countersunk, and each contain a small plastic grommet that the spray tip of the injector fits into. These little round rings can easily slip out of the head when the injectors are unbolted and extracted. Take care not to lose any of them as new OEM ones are no longer available.
2. The small sections of rubber hose that connect the injectors to the rail slide onto "barbed" metal nipples at both the rail and injector sides (under the ferrules). Never use a knife to cut a slit in the old hose when attempting to separate it from the metal pipe nozzles, as the sharp, one-way barbs that hold the hose fast can easily be damaged by a blade, and cause a leak when the new hoses are installed. For that reason, the shop manual recommends using a soldering iron to "melt" the rubber at the fittings to separate them from the nipples without risking any destruction to the metal barbs.
