So I'm going to seafoam my engine, but want to make sure (this is my first time) that I'm doing it right.

I'm going to use the brake booster vacuum, which should suck the fluid into it, right? About 1/3 can into the vacuum line is all I need?

And just for clarity (since I'm a novice at this), the pic below shows the correct vacuum line, yes? Just disconnect it from the brake booster, let it suck out the seafoam, wait a min, kill the engine, and then start it up 10 min later?

Here's the pic:

that is the correct line..........

Thank you sir!

What is seafoam? I haven't heard of that before?

Do a forum search on it, you'll find tons of threads

Dump some in the fuel tank also. And while at idle, spray the throttle body with some cleaner, you can use the trottle cable to increase rpm's a little while spraying the cleaner.
