this is on a 95 z28...does anyone know what this part is?its got a vacumm line plugged into it, and its about 8 inches long, cyclindrical in shape, and mounted to the bottom of the front subframe rail on the passenger side behind the two horns. its in the way of some of my turbo plumbing, and im wondering if i need it, if not ill relocate it

 

vacum resorvior, I'd relocate it, you'l need all the vac storage you can get when you boost
