yeah I fill em up like Rob...I don't have one o them fancy schmansey air suckers like you high fallutin peepoles got though....I just use zip locks.....Great planes makes a package of rubber caps...I use those and they seal every orifice in my mills cept the fuel intake, I use a fuel tube clipping and zip tie that closed.......also use a blown glow plug when you go to store it filled with ARO, all the ARO on a new plug could blow when you go to use it later (the oil will stay on the element coil and if you shut down before burning it all off you super cool the element and you get a blown plug)..I keep a few blown ones and pull the element out so I know it's dead.....when you go to run it again, just drain it for a while on a paper cup or towel before slapping it in your ride.....
