Sorry to go against better judgment. I ended up getting that little piece out of the intake, it's now soaking while I figure out what to do with getting a fitting/hose that works. I'd still like to go OEM, but can't find anyone that sells 'em. Guess I'll hit the dealer and see what it's gonna cost. In the mean time, a friend sent me a booster vacuum hose, but it appears to be from a different LS motor (he has both an LS1 and 5.3, don't remember which he sent me) because the fitting is different and won't fit in the hole in the back of the intake. Now that I have it off, I could just plug it and run with manual brakes for the meantime, but its a short term solution
