Hi
I would also say check it! Also I found a load of sludge inside the lower metal casing when I removed mine, well worth removing that and giving a good clean out.
I would suspect that the later engine pump is the same as the change on height for the 2.0 was due to block height, not sump area related, but you would need to double check. I see the odd one available on Ebay.it which is OE according to the listing.
