98 XJ Vacuum Canister

I'm currently replacing the front bumper on my 98 XJ. I've suspected I have a bit of a vacuum leak (cruise control can't keep up under heavy load, sometimes the A/C switches to defrost), so I figured I might as well replace the vacuum canister behind the bumper while I have it off.

I searched around and couldn't find the right part online. I ended up buying this http://a.co/cXIFg3Y (Dorman 47077) because it came up when I did a google search of "98 XJ vacuum canister" and looked very similar to the one I took off. However, once it arrived I realized it was actually much bigger, see the size comparison (New Left, Original Right):

Does anyone know where I can get the original vacuum canister, what is the part number? I am struggling to find it.

Alternatively, the vacuum canisters look like they have the same input/output, would there be any problem using the bigger canister? It seems like it would provide more reserve vacuum during heavy load and might help address my problem; am I missing anything?

Thanks

The hard part is finding it/them. Other than that make sure it is pointed the correct direction when reinstalling.
