Yea, Crazylev is right. I just re-installed it this past Sunday. I plan on updating with some photos later. I would not re-use that POS alum line. I spent maybe $15 on my fix which thanks to the posters of the linked thread got me to where I am now, a fix that will not break, is not over torqued or stressed which caused it in the first place.
There really should be a reacall on this oven. This is a potential issue of some significance. Three things you don't mess with, things that burn LP, your running gear or your hitch.
