I found this hose that came with a wet vac that I bought at HD or Lowe's. Whichever one it is sells the 2 different size hoses and related accessories. I've found that those 3-5 gal wet vacs work better with the small hose so I usually shit can these larger dia hoses that come with them, by the adapter and use the 1 7/8" small hose instead. I decided to see how close this old hose was to the unobtanium OG hose and damn if it isn't tight as hell. It's an ID fit vs. an OD fit but cheap bastards don't let these things get in the way. I wouldn't use it in the engine compartment but I'll bet it's fine in this area. I'm not pursuing this as I'm going water cooled and will use this space as a conduit.
