Ron,
Need to make one up yourself.
You'll need:
#1 A length (say 3 metres) of 1/4inch air hose, and 6 clips
#2 A 1/4inch brass barbed-T (can usually get them from the brass fitting section of auto or hardware
shop)
#3 Two tyre chuck connectors. The two tyre chucks need to be able to flow when there's no valve in the stem, they need to allow a reasonably high flow, and they need to be able to clip onto the valve stem. The ones that come with most of the good tyre pumps are good.
#4 A cut off tyre valve stem from an old split rim tube.
Cut the hose into 3 lengths - a short length to the valve stem fitting, and longer lengths to the two chucks. And assemble it so the 3 lengths come off the T.
So when using, you
#1 have the "air tank" tyre pumped up to max pressure (usually 65-80psi).
#2 Remove the valve core out of the flat tyre.
#3 Connect your tyre pump to the valve on the Tconnector, and start the pump. Hook one chuck onto the flat tyre, then hook the other tyre chuck onto the airtank tyre, and you'll get a heap of air flow into the flat tyre to reinflate it. You can make the flow faster again by removing the valve from the donor tyre. Usually have the flat tubeless tyre standing upright as you try to inflate it.
Ony time I ever need it is if reinflating 265 wide tyres on 8 inch rims. All my rims are 7 inch, and are not a problem to simply inflate off a pump.
Some people have a simpler system - a single length of hose, with a tyre chuck on each end, and don't have a pump going.
Cheers
