new ZR1 owner with a few questions. - ZR-1 Net Registry Forums

I have recently purchased a white 1991 ZR1 with 70,000 miles. The car is great, just needs a little paint work on the front bumper and some maintenance items taken care of. I usually don't post because I find everything I need to know form searching. I never had to ask anything about my 03 Z06. I have access to all the tools I need and a lift. I'm also pretty good at working on cars. I plan on removing the plenum and and replacing plug wires, coil packs, spark plugs and injectors while I have it off. I will be using the Bosch injectors from FIC. I will also change the PCV, thermostat, oil, brake fluid, transmission and rear end fluid just for peace of mind. My question is I have a small vacuum leak that needs addressing. What parts would I need to replace while I'm under the plenum to after I find the leak? Would the standard vacuum hose rebuild kit from white racing address most of the area under the plenum and if not what else would I need and where would you get it? Also at appears the secondary vacuum pump is bad, I will remove it and see if it is a simple problem but if it needs replacing I read there is a GMC truck that uses the same pump, just different connector. Where would I get that from?
