My opinion anyway.
I had nothing but trouble with my stock petcock.

It wasn't leaking from the connection to the gas tank; it was leaking from the switch! This is because the valve on the petcock is just two small holes and the switch just moves a rubber washer with 4 holes over it(that's why there isn't a hard on/off position). Also, the switch didn't align with the "on/off" positions, so I had to figure out where it would turn off.

I switched out my petcock with a brass spout and an inline plastic petcock from OSH.
