Weber Q Gas Grill Burner Replacement repair fix
I ordered my replacement parts through Weber Australia (1300 301 290) They were super helpful and had my parts out within a few days.
Just make sure you have your BBQ serial number handy when ordering.
For reference my Weber is from 2016.
Part number is 65062.
Parts can be found on a few other sites but Weber was the much cheaper option with free delivery.
