You slide the pointed end underneath the hose, move it around and the hose pops right off..... About $10 on Amazon, works on any size hose.

Thanks. I have this instrument from Harbor Freight. My primary question was what does this hose do ? Will it leak coolant when I take it out ? or is it some vacuum hose or something ?

Thank you.

It looks like a coolant line.
