The VIR which is a canister jammed down into lower fender area of the passenger side. It has 2 large O-rings that leak. After finding and correcting the leaks, you'll be changing out the desiccant bag in the VIR and the kit will come with a new O-ring. Unfortunately it doesn't come with a top O-ring.
Odds are you have several small leaks and the hoses are porous, especially if you're not using R12. If you want a reliable system, replace everything mentioned above, have it pressurized with dry nitrogen and trace of refrigerant and then checked with a high quality electronic detector.
Few tips:
When you're trying to get at the VIR, there is a small panel you can remove from underneath the car that allows access. You'll want long extensions and a swivel for your ratchet as there isn't much room around the VIR.
You need to remove the hood to disconnect the hose at the top of the condenser. Always use a backup wrench on every fitting.
