LS6 Vacuum Nipple Size Does anyone know the size of the vacuum nipple for the brake booster on the LS6 manifold by the MAP sensor? I tried to put a 3/8 hose on it last weekend but it's larger than that. I have a 3/8 on my brake booster check valve so was hoping it was the same, it is not. I attached a pic for reference. Obviously, I'm speaking of the larger vacuum nipple. thanks

I believe its 1/2". I remember using some sort of heater hose adapter to hook to my 3/8 booster line.
A trick I've picked up for forcing a hose onto a slightly larger nipple is to thread a bolt into the hose, warm it with the heat gun until it gets soft, and then it will hold the flared shape once its cools down.
