Quick question on adding Seafoam through the vacuum line on my 2005 Ram 4.7. The vacuum line has extra hoses coming off it. I'm not sure what they are. They look like 1/8" and they split off and not sure where they go. Can I still add Seafoam directly through vacuum hose or do I need to disconnect the smaller hoses coming off it? I can add a picture if that helps.

 

Here is a pic of my motor. The red arrows are the small lines that I'm not sure of. The blue arrow points to the regular line I would normally add Seaform to on other previous vehicles. Thoughts?

Thanks!
