Yes, that hose has different sizes on the two opposite ends! It was quite vexed by this when I first discovered it. I ordered mine from Zip but there's probably other sources that will work.

Just get a length of hose or elbow the size of the smaller of the two ends. Heat gun/blower dryer to heat up the other end and slip it over. Just did all the vacuum hoses on my '96 and there are a couple like that. It's cheap and you don't have to wait on shipping.
