its a big (kinda) tube that if looking at the brake booster (thing the Brake Master cyl. connects to) it will connect on the left side...and it goes from there to in front of the engine...

 

i used that stuff a few months ago..i big old cloud of white smoke came out....just use one of your vacuum lines...that would work fine..i noticed a big difference after i used it..

 

if it says to use the brake booster line, use it. go pop the hood and look at your brake fluid tank. the round thing that your brake fliud tank is right next to (toward the steering wheel) is your brake booster. there is a black hose as big around as your pointy finger that goes from your brake booster to your engine. this is the vac line that they recomend to use. use it.

 

I just did it, and there wasnt really much smoke whys that could it just be theres no carbon buildup lol? theres gotta be some its a 97

 

Could take a picture of which tube you used if you're not sure which one...

I'm rapidly getting tempted to seafoam my car out...

 

Im pretty sure it was the brake booster one cuz it was sucking air in when i took it off.

 

I want to do mine, but I would have to do it anywhere but my house, the neighbors would belly ache about for the next 50 years...

 

Hmm, would it be the hose that connects to the check valve on the brake booster cylinder?

 

had like a little wire connected (and maybe 2 wires depending on if u have ABS or not) and on the upper left side of the brake booster(if looking from front)

 

Or you coulda done my sprayt bottle method, works every time and dont need to locate any vacuum lines, just pop off air filter assembly off the throttle body. If it sucked it all in but didnt make a bunch of smoke, its in there just not getting used. Rev it up a little
