15# CO2 canister from a fire extinguisher store ($100 + Fill ups are $15-20)
- This will fill you up 8-10 times (sets that is)
150# regulator
1 Hose kit from HD or Walmart
1 Air gauge/filler
You might want to make a short 2' hose connector and just carry the tank to each wheel. It takes 40 seconds to fill up each tire. You can do multiple vehicles at once...
