This guy pulls the vacuum line off like It's butter , my vacuum line isn't budging , is there another hose that I can feed the sea foam through ?
Or is there an easy way to take it off ? ( I tried removing it with the car off btw)

 

In the VID, I am SURE he might have practiced or prepped for the vid....
After nearly 10 years of baking under the hood, I'm sure most every hose is gonna be stiff and stuck.
Just have to work it...

 

use a pair of pliers or channel locks and twist the hose left and right as if you were tightening and loosening a bolt then use your hands to pull it off the nipple. WD-40 helps too if its being really stubborn

 

I'm honestly afraid of cracking, It's a hose that's so old it could still crack
