Gas Tubing

Pull oven power and turn off gas (mine was off)
remove six screw that hold the back cover
lift the back cover off and set aside
The tube runs from the regulator to the burner valve assembly (manifold?). Un-tighten the two ends gently and remove old tube.
Apply LP gas leak goo to the threads (don't use teflon tape) Align the new tube and finger tighten the nuts. Make sure you get at good seat on the connector by pressing snuggly (not too hard) the tube end into the recieving unit and then carefully tighten with the wrench until it is snug.
Be careful and turn on gas valve.
Listen for leaks. (turn off gas valve if leak found)
retighten a little more and re-check. If still leaks you have other problems like cross threaded nut or a bad seat. I would order a new part if that is the case or call someone with more experience.
If no leaks, replace the back panel and the 6 screws. Plug the power cord back in and give it a test run. At first there will be air in the line so it may take a moment for enough gas to reach the burner.

For the courious, I bent it when I lifted the burner top up to peek under to fix a differnt problem with the ignighter. Note to self: Un hook the tube first if you need to look under the burner unit. :)
