So when I bought my sanke the guy gave me a co2 tank, regulator, beer faucet, and shank. All these items sat out in the weather for years. I was wondering if it would be possible to rebuild the regulator. The gauges seem to be the parts that didn't handle the weathering very well. I was hoping that I'd be able to replace the gauges and wouldn't have to purchase a new regulator. Thanks in advance.
