67 Camaro Build

[Lost in the 60's]

Expensive lessons usually stay with me longer....
I went thru the same thing 40 years ago, working for a bus company that all the air and fuel lines were made that way with stainless braided over rubber. A little spit on the end of the male insert goes a long way toward insertion success...
I learned to use duct tape when cutting the line to avoid unraveling of the jacket and steel. Place the tape so the cut is in the center of the tape width. The trick with that, is to peel it off laterally, rather than circular. Helps to keep the stray wires in place for the nut to go over easier.
I used that method for the next 38 years on my own semi repairs.
