i am replacing the fuel lines on my 69 and was wondering what you guys would recommend. i am thinking about going with aluminum tubing but i'm not sure. thanks
If your not looking for the luster of stainless aluminum will be fine.
Vibration will not harm it......airplanes are 99% aluminum.
Aluminum will not bend and flex like steel it will crack as steels will bend more.
My 73 had a 3/8 fuel line, 5/16 return and 5/16 to the vapour canister.
Any problems with using all 3/8 Stainless to replace all of them?

edit for spelling
I just went through this today with my engine builder. If it is a healthy BB or a wild SB it should be 1/2. I told him I was doing it in 3/8 and he chastized me
He stated a 3/8 line would flow nowhere near my needs given 600HP requirements and said that even my old 427 was no good with 3/8 lines. I asked what I should do about the return line, he was noncommittal so I will leave it stock size for now as I am too lazy to swap it out as well. I was surprised, I have a good fuel pump as well.
