ABS canisters have to be exchanged. You won't find anybody locally to fill them because the empties are sent back to ABS to get filled with nitrogen. You're in Georgetown correct?Butterfield express in Chubuck is probably the closest one to you in Idaho. There's a couple of ABS dealers in Logan if that's closer to you. ABS has a dealer locator on their website. I called and price checked Butterfield's earlier this year and they were almost double what Carls in Boise was for an exchange.
