I'm finally at the point where I'll have my 1990 TII running soon, but I'm having a bit of a problem with the vacuum line system. On the LIM, there's a small valve(?) that's positioned slightly above the primary injectors, and there are two vacuum fittings on it. One of the hoses is extremely long, and is covered with a sheath, and the other hose is missing. I need to know what this valve is, and where I need to plumb it's hoses in.



Also, on the LIM, there's a vacuum line that "bridges" between the secondary injectors. This line is NOT in the FSM, or at least it's not on page F2-7. Why is this not listed, and where do I plumb the line for the secondary air-bleeds to? Am I correct in assuming that the nipple that's on the firewall side of the LIM is the nipple for the secondary air-bleeds?



I'll see if I can get pics...I don't have a camera nearby.

 

Is it the same as in this thread?



Pictures are further down on the page.

 

Yeah, that's it. Mine looks different, as it's a S5, but it's still the same thing.



I'm just going to cap it off.



Also, do you know anything about the vac. lines for the secondary air-bleeds, and where the line goes?



Thanks.
