Late thanks for that info 88Stanger, if I ever get this truck back together I wont be racing but will be driving reeeeaaall sloooow until I make sure the brakes I redid actually work. Never touched brakes before so this will be either a wow I actually did it or a I never should have done it myself moment.
I did get a reply from the site I mentioned. Although the contact I had focused on the brake application and not fuel here is what they said
My Question
Hi, Ive read an article on your site about brake lines being safe for copper nickel/ cunifer lines. Is there any data or information that shows that copper nickel/cunifer is ok for fuel and transmission lines? I was going to replace the lines on my truck and was told that copper might not be safe or compatible with copper. Thanks.

https://www.copper.org/applications/...ube/brake.html It also identified copper-nickel alloy C70600 tube as outstandingly superior to conventional steel brake line tubing in laboratory salt-spray-exposure burst tests. There are other supporting technical papers listed there. "
I saw on their site here some good info on corrosion
https://www.copper.org/applications/...oklet.html#2.3
Table 18 rates corrosion resistance to different agents. Petrol is top rated with a 1. So is beer, good to know. So I will be going with copper nickel all around.
