im just finishing up making fuel lines and emissions delete on my s4 13bT. I am using the "rotary Resurrection" emissions delete guide http://www.rotaryresurrection.com/2n...s_removal.html

My question is in one pic it seems I have an extra vacuum port, on one side of teh TB, mine has 4 and the pic only shows 3, what is the bottom one with the filter for? should I cap it off. also what is the middle one that is uncapped for?


Mine:


the picture from the link


EDIT: I just noticed that it seems like I have an extra one on the top rather than the bottom which I was thinking, so technically I have the wrong ones capped off. should I just cap the extra top one? but I would still like to know where the one where it is uncapped goes to


Thanks,
Mathew

 

So I think the middle on in this pic(one capped with red nipple in my pic) is for the omp could someone check this out for me? I figure im just capping them all considering im not running an omp.
