Maintenance/Repairs

I am going to be replacing the intake manifold on my truck as the gasket is leaking. I guess I am a record on the stock gasket. Anyway, I have been told you need to replace the injectors and the plastic manifold as well unless you want to be repeating this process again in the near future. Everything is original and this this is a 2WD 5 speed manual if that matters.

Are there any upgraded OEM or aftermarket assemblies? What is the best thing to buy to replace this? The shop I use said they would just buy the AC Delco but that there might be something better to replace the injectors with a better design. This spider injection is apparently not one of GM’s best ideas…

They also think that the fuel pressure regulator is leaking externally as there is a gas smell and the truck has to build fuel pressure before it starts if it sits more than a few minutes. They basically told me not to mess with it now if I am going to bring it in shortly and just have it all done at once. I have another truck in the shop and will be swapping this one when that truck gets picked up.

Are there any kits with all of this or do you suggest buying certain brands of certain components vs. buying all as a kit?

Thanks
