I got my petcock today. I found two brass barbs, one with male and one with female threads on the opposite side and screwed them together with some yellow teflon tape; this allowed me to use the original hose to the new connector, and then the 1/4 hose to the new petcock. I ended up needing to reroute the fuel line so the line is a bit longer now, but it works great and fires up first time.
