I've decided to disconnect the hoses from the evap on the firewall side & see if I can figure a way of pulling a vacuum on it.

I'll see what I'll need to perform this after I remove those hoses.

In the mean time, I'm going to order everything new under the hood except for the compressor which is only 6 months old.

So far, Amazon has the best prices on everything I will need.

I'll update what I find out. I just hope I don't have to pull that dash out..
