1973 Opel GT
Thanks. I've used copper line before (not on a car), and it was way too easy to bend and screw up. I guess the nickel added to it adds enough strength.Just because it can be “bent by hand” doesn’t mean that’s it’s soft and breakable, like pretzel dough. These lines are strong and require effort to bend by hand, they aren’t like pipe cleaners. I used Earl’s Easy Form Hardline Tubing for my EFI lines. While you can “bend it by hand” it is best to use a tube bender as pictured previously. You have to put some serious force behind it to damage it. It’s widely used for a reason and is worth it.
