Yes you would need a few things. A vac pump. You can get one from harbor freight for about $100. Don't bother with that cheap air compressor attachment one. You need a manifold gauge set. I think $50 at h/f too.
Here is a list to show what else is needed for the compressor repair.
You can search ebay for a full kit like the one I bought.

Another essential part you need. Do not think you will get the seal on without damage you must use the following tool.
Part SPGM - SEAL PROTECTOR DENSO 10PA / GM LIP SEALS-SPGM <----- its the last one listed on that page at the bottom showing it can be used on the V5 compressor.

This next tool could technically be optional if you plan on tearing the compressor apart since you could knock the seal out from behind. But its helpful when you go to reinstall the new seal.

Here's the loan a tools you need from autozone.

clutch hub puller and installer.

You could probably get the loaner clutch holding tool too but I'm a pretty strong guy and im able to pull/reinstall hub by just holding it with my hand.
You'd also need a bottle of pag 150 oil and I prefer to coat all my new o rings with stuff called Nylog you can easily find it online. Although its not necessary.
Anyways that's just to give people an idea of whats needed for the job. I have a lot of projects going on but I will get it done slowly in the near future and give updates/instructions.
