seafoam brake booster or vacuum line?

Which is best for even distribution to all 6 cyls? And where would they be in the SM? I tried searching thru it but didn't find them. Do they have different names?

 

brake booster will suck it up, sooo it is a vaccum line...

1/3 brake booster
1/3 gas tank
1/3 with your oil

Thanks. Ya I did a few searches, that's how I knew it had to be the brake booster or vacuum, but I never saw that one thread. Thanks for the link.

I've had a can of seafoam foe a few months now but I just realized the can I got is the seafoam spray can. It has a spray nozzle like a wd40 can. Can I still use that?
