I am trying to run new fuel lines on a 1970 Chevelle. I have heard that I need to remove the body from the frame to do this, but I do not want to risk doing that because I can potentially damage my car.
1) I am wondering if it it possible to run new fuel lines on this car without removing the body?
2) Also I think that if I cut the fuel lines I can install them without removing the body but how dangerous is it to cut a fuel line a reattach it afterwards with a flaring tool? I have heard for safety reasons not to cut fuel lines.

As you were told at the other forum, it you plan to use pre-bent lines, you would have to remove the body to do it without bending them.

It's probably 3/8 but you need to measure the old ones
