What year? If you have a 1989 or later, you have no problems. If it is a 88 or before, buy the fuel rail off of a 89+. The PD is the piece on the end of the fuel rail. Of the earlier models, it was a separate piece on the fuel rail. On 89+, it was a part of the fuel rail.

ahhhh my experience is needed
ok all you need for the switch is the 89+ fuel rail. and a couple of nuts that will fit over the bolts that hold it in (89+ bolts will work if you can get em)
take off your intake manifold and unhook the fuel lines from the fuel rail. (you may want to do this and leave it for 15 minutes cuz of the fumes) oh yeah cover your lower intake with something so you dont drop anything down there. remove the bolts fron the fuel rail and take the injectors out. if the O-rings are ok just put some vaseline around them, if not you must replace them. the 86-8 bolts are too long for the S5 fuel rail so you have to thread a nut all the way down on each bolt. then put it in the place of the S4 fuel rail
that whole thing is fairly simple if you are good with tools. oh yeah you have to get new fuel lines because the S4 ones arent the correct length, just remember to get high pressure fuel line for fuel injected engines. .
any questions???
