Brake booster line?

[Ghost_007]

Hey guys I just cleaned my TB and MAF sensor and the next thing to do is to Seafoam. Can someone fill me in on where exactly the booster line is? I see the brake booster assembly and what not, but not sure which line is the booster line. Truck is an '04 Z71 Tahoe...thanks for any help guys...

The big rubber one going to the engine from your booster.

Is this big line on top the one I'm looking for?

That large line up top runs to the power steering reservoir btw...

Ok, so I've been doing some research and it seems I might have the Hydro-Boost instead of brake booster line? Now I'm really confused...

What you want is to put it in this line. It looks very stiff, but it is actually flexible and it just pops right off.

Little closer view.

Also, if you want to make it a little easier on yourself then remove this piece, just one screw. Not necessary, but it will help.

Good luck.

Thanks dude...I ended up adding the Seafoam to the hose right behind the TB on the left side, but I got absolutely no smoke when it ran afterwards. Either I've got a really clean engine or I need to try to put the Seafoam in the hose you've shown above, lol... Might give that a try tomorrow...

I got very little smoke on my first time as well. I heard you get much more the second time around. Guess the first time just loosens it all up.

Makes sense, thanks man...

I have a question regarding that line, when I pulled it out the suction was pulling towards the top end, that is where I need to put the seafoam correct? Not in the right side end...
