To give some context, me and my friend (he's a mechanic) were able to figure out that my fuel injectors are leaking - it would leak even when the car is off, which would then result in a big cloud of smoke when I start my car after +1 hour of sitting with the fuel being burnt off My car is the 4.2L, has 96k miles and I've recently replaced my spark plugs and o2 sensors; I'll most likely change my coil packs as well. But my main question is what else should I replace while I have the supercharger and intake manifolds off? Any gaskets, hoses, or other preventative things items?

We're wanting to do this is in about a week or two so I have some time to order items. Thanks!

On the 4.2 L, if that's what you have I would do the valley hoses that go from the back to the front.

If its all coming off anyways…
Supercharger fluid.
All coolant hoses
Heater hoses??
Throttle body cleaned??
