It doesn't really matter which vacuum line that you use as all of them will suck back into the intake. Just make sure that there's no device/valve/part between the line and the intake. If the booster line is accessible then use that. If not, then simply choose another as there really is no "best" line to use. I mean if it were me then I'd choose a bigger line than a smaller one so that it might atomize/mix the cleaner a bit with the air and use a rag or something to keep it from leaking out. However, it will make little if any difference.Which vacuum line is best to use when spraying in the CRC cleaner? I’ve heard some will spray just before the throttle body but I’d like a more direct path. I’ve heard some say just to pull the brake booster line and spray within that. I just feel there’s a better more direct path than those two routes but don’t know enough about the vacuum/pcv system to locate the best line. Any help would be appreciated as I’ll be doing this in the next 500 miles.
It depends on your car and where the vacuum lines meet the intake manifold. Find a line that feeds all cylinders evenly, if possible. With plain air, that doesn't matter. But when you add liquid or spray to the mix, it's heavier than air and won't self distribute as easily.do you have a picture of a good vacuum line to use
Lol, excuse me? You haven't a clue dude. YOU'RE WRONG.Wrong. Bigger line means less pressure, not more.
The benefit with a bigger line like the booster line is that it will pull some air in along with the cleaner compared to a small line which will be pulling in almost all cleaner. It will help to distribute the cleaner in the intake more evenly. Most brake boosters are buried under the cowls these days therefore anything after the MAF will be ok to spray into and preferably into the throttle body. Spraying on the MAF would NOT be ok.I'm a super n00b when it comes to cars, do you have a picture of a good vacuum line to use?
Thank you in advance.
Wrong again.You haven't a clue dude
Nope, you are talking about force of vacuum on a surface. I'm talking about an open vacuum line to the atmosphere at least in the case of my bigger line anyway. If you put a tube squirting fluid into a vacuum line that takes up the same size as the vacuum line or almost the same size then you will suck in almost no air if any air at all. Thus, no atomization occurs thru that line because it's completely liquid.Wrong again.
A given vacuum applied to a larger surface area creates more force. Pressure is measured in PSI, pounds per square inch. The more square inches of surface area with a given vacuum, the more total force. That's why the brake booster line is bigger, to apply more force to that component.
But when you disconnect the vacuum line, the vacuum is broken, and air flows through the line. Bigger line, less PSI, and less help atomizing any liquid.
This is why Seafoam stopped recommending liquid in vacuum lines. Because many mechanics are not smart enough to think things through.
Big difference between "same size" which allows no extra air flow vs "almost." The "almost" creates more intake air pressure. A big fat line provides little to none.same size as the vacuum line or almost the same size
You're a genius in your own mind.I can see that you can't conceptualize this concept
It's not a big difference between same or almost. The little line is flooded with cleaner which btw is squirting at pressure. The larger line still has plenty of suction to pull in BOTH air and cleaner. "Provides little to none" is not only an exaggeration but a complete fabrication. A brake booster line has plenty regardless of what you say and if it provided none then it would be useless for making the booster operate. You like to try to twist things in your favor but it just isn't working.Big difference between "same size" which allows no extra air flow vs "almost." The "almost" creates more intake air pressure. A big fat line provides little to none.
And that only matters for liquid, not spray. The spray is pre atomized by the carbon dioxide in the can. Look at the MSDS for carbon dioxide.
