How many miles are on it? I'd replace the chain if its got over a 100K on it, just to be safe. Usually the kits come with everything you need. Stock fuel pump and injectors will be fine too for 5 or 6psi. Make sure you have good oil pressure, if you get a supercharger what pumps oil from the pan to the unit.( vortech does) www.vortechsuperchargers.com Go there you can even Download the parts list for kits and Installation Manual.
So you should'nt need anything extra.

I would not recommend trying the stock fuel pump and injectors. Unless you like changing headgaskets, I would at least upgrade the fuel pump and get an fmu to go along with the stock injectors, or find some 24 or 30 lb injectors and run without an fmu. Better to be safe, than sorry.

The Vortech kit should come with a FMU supplied. With a FMU, you should have no problems running stock injectors and fuel pump...HOWEVER, the FMU is just a "band-aid" for the fuel system. If it were me, I'd ditch the FMU and just run a bigger injector and fuel pump.
