I have a question about the waste tank on the spit fire 3.2. I was about to install an auto pump out. But i was wondering if i can put a bigger waste tank in? Would i loose vacuum power? Should i just do an auto pump out?

they offered the 70-80 tank as an option, so you can go bigger, but unless you really have a large job or even a lot of larger jobs, by the time you fill a 50 gal tank, chances are you might need a breather, drain the tank, check the chemical jug, move some hoses around and maybe a little prespray and fire it back up.... it doesn't take long to empty and your body will appreciate a few seconds rest..... same think with the pump out... doable, but why bother.....
