Re: Ford Explorer 1997 (petrol) fuel system
I've never seen anyone quote themselves on here...til now.
Anyway Sandy. I couldn't find any photos in an old repair manual that I have, but first you'll have to acquire the parts. Then, depressurize the fuel system. There are a few ways to do this, the easiest is to remove the power cable to the fuel pump, so the fuel in the line will gradually be used, or returned to the tank via the return fuel line. The engine should stall out within a minute. You'll have to remove the intake assembly, only on top of the engine, then remove the fuel rail (be careful, as there might still be a hint of pressure, but nothing to overly worry about). After you remove the fuel rail you should be able to access the injectors. If the wiring isn't very long, disconnect the injectors and you should easily be able to pull out the O rings and replace.
One thing I would do first, if you have the means, is to cautiously use compressed air and blow any debris/dirt from out around the top end of the engine. This will prevent any crap from falling down into the cylinder as well as giving an improper seal on the new O-ring.
