Figured out that you can't really take that off. So I returned the pump I bought, and got the correct one. Autozone and Advanced Auto do not carry the power steering pump with the EVO. O'Reileys does carry them. They are $116.99 with an $80 core charge (at least that was here). So make sure you take the old pump in first so you don't pay that. After about 2 hours, I got the new pump in, and it's running great!
Only thing is the high pressure line. It's leaking a little bit right where it enters the pump. I think it's in just a tad crooked, so I'll fix it tomorrow morning.
