Adding Seafoam to 2008 Yaris vacuum lines

Hey guys, I'm inexperienced when it comes to anything outside the usual maintenance of my car. I was wanting to know how to use Seafoam in my car's vacuum line. Any help would be appreciated.

My suggestion would to not do it. So long as you are running "Top-tier" fuel, there is no need for it. The fuel has enough detergent in it to keep your fuel lines clean, and the engine runs hot enough to prevent oil sludge. Is there a reason you feel it's required?
Cheers.

I wouldn't use the vacuum line method, as I recall when I did a seafoam treatment, I found out to much can go wrong using the vacuum hose. I opted to do the spray method.

However, after watching the video below, I now question if Seafoam is the stuff to use.

in a properly maintained yaris I wouldn't recommend it.

That being said I've used it in my '02 Echo to help it pass an e-test with a P0402 cat converter code. It cleaned it enough to allow the ECU to only not ready one check which is good enough to pass where I live.

I used the spray and the straw to spray it into the air intake.

I've also used it to help clean the valves on the intake side when I had the head off (didn't want to remove the valves to do a full clean)

Run a good oil with proper change intervals, use a decent fuel and take care of the car and it will run forever without needed additives. Just my $0.02

seafoam

I have used it before in other cars and if you're gonna use it through the vacuum line remember to use a clear 3/8 hose with a tapered end so that it only sucks a little at a time from a cup. 4-5 ounces is enough. DON'T SUBMERGE THE END OF THE HOSE INTO THE SEAFOAM. With the tapered end it'll slowly suck it in.

Are you going to use this Seafoam to cure a malady with your car or is it something to give you piece of mind.
My 08 sedan just turned 200K kms and is running perfectly with no need of any seafoam treatment.
If it aint broke dont fix it.
