Tubes and hookups on the back of an LS1 intake manifold Ok, on the back of the intake manifold there is one larger tube that hooks up, 1 electrical connection, and 1 smaller tube.
To help the face mounted air vents will not work if the smallest tube is not connected to the intake manifold (in the back).
My question:Where is the oppisite side of that tube connected?
After my cam/heads swap I forgot to plug this in, so I have an intake manifold air leak, and no face air vents. I can stick my arm back there and hook it up, but I can't seem to find the tube (hopefully I didn't torque it down under neath the intake manifold). If I can find where it comes from I can trace it to the intake manifold and see where it is at.

Re: Tubes and hookups on the back of an LS1 intake manifold There is severaly tubes back there. There is one that comes off the brake booster that snakes around behind the intake. Then there is the A.I.R. pump which has 4 hoses to it (3) 5/8 and a small one on top. There is also a little bracket mounted on the fuel rail or whatnot that has 2 nipples for small tubes. The top one, which is closest to the hood goes to the top of the pump. The one below it goes to the intake where it tees in to another fitting. The 3 other 5/8 hoses are the A.I.R. hoses. Hope that helps
