Shift cable housing problem

I have installed an old Simplex front derailer and when I shift from the small to the large chainring, the section of cable housing at the bottom bracket "kicks out" away from the frame. How do I keep it from doing that--short of duct taping it the frame? See pix of the state of the housing in low gear and in high gear.

That shot of the bb looks exactly like my 1970 Raleigh Grand Prix. What bike is that? The braze on cable guides and routing of the front der cable are exactly the same. To not help answer your question: mine does the same thing when I shift. Sorry.

Do you have any extra cable housing?
That housing shown may be a tiny bit too long, but don't experiment on it by cutting it! Try a peplacement piece first.
Just a guess.
Good luck.

Thanks, chajmahal. Although I appreciate everyone's suggestions, I like your's best because it doesn't require that I do anything. Sweet! The bike is a 1972 (best as I have been able to tell) Raleigh Super Course. There are more pix at https://www.doug-morgan.com/Raleigh1972/. Another idea I will persue once I find a cable housing reducer, I'll try putting that on the forward end of the housing and see if that stops the housing from pivoting in that cable stop. Also, I'll check out teambhultima's idea about the lenght. Thank everybody. I love this place.
