i do carry a spare 1 Liter bottle in my hatch that I keep a w/m mixture in.
i got the bottle from a friend that works in a research lab so I feel safe transporting the meth in it as it is a sterile bottle, thick threaded screw on lid and its made of some sort of plastic mixture that wont get eaten up by the w/m.
I would research all of the vendors and pick out what w/m kit best fits your needs.
I have the DO DVC30 kit and really like it. It may be overkill for a k03 but I liek the way it functions and it will still work out nicely if I upgrade my turbo later on.
