Ok i feel dumb asking this but where is the vacuum lines and which one feeds all the cylinders evenly im doing the sea foam treatment on my 4.9l l6 and it says IMPORTANT: before any vacuum lines are used make sure the lined feed each cylinder evenly. i just don't want to mess my engine up more then it already is. PS im going to take pictures and post a step by step guide in the how to section for sea foam the wonder treatment!

 

Your brake booster hose is what you need to use.

 

ok thank you I just wanted to be sure because im not experienced with vacuum lines or breaks systems as much.
