I've been installing the vintage air system, I thought buying the individual ends and getting the hose local was a better option because I needed more fittings then came in the kit but now I know better. Local supply charged me 140 dollars for just the hose, I got another 300 in fittings. My suggestion, buy a kit then add additional fittings. I bought a manual crimper tool and it's easy to operate and crimps look good.
