Can someone guide me to change the air tank?

Can someone tell me what I need to change the air tank on my Vulcan 3, I have a 580cc tank as original equipment and I want to change it for a 700cc one? alsafe

Unless that bottle was purchased from a vendor who built it specifically for that Vulcan, you may need to buy the correct bottle valve for it. Or, carefully remove the valve from your 580 tank and move it to the 700 tank.
P.S. safely remove the air from it before you try to remove the valve.
Thx

Hopefully all of those details were discussed somewhere upstream. If not carefully go with Dan's suggestions.
