Good afternoon,

You need to pressure test the system with a pressure tester. That will tell you if it is a hose. There is a separate adapter for pressure testing the cap itself.

I attached a guide for you to view.

Got it.

Do the pressure test I asked you to do. It looks like the cap but you need to be sure.
