Default Help with oil pressure sending unit

I have a 2002 Olds Alero with 3.4 engine. I need to change the oil pressure sending unit. I see it'* located next to the oil filter and shouldn't be much of a problem. Can someone tell me the best way to remove the old sensor? Should I use a socket and if so what size is it or can I use an open end wrench and just remove the oil filter?

I used an open end wrench and removed the oil filter for more clearance only because I did not have the right size socket. A socket is easier if you have one that fits.
