Worked great on my 2008 Duramax primary fuel line, I removed the section of steel line just behind the fuel cooler I used 1/2 rubber hoses to 350psi (those steel quick couplers are useless where they're spraying the streets) and put a new transfer unit in the fuel tank. I didn't want to cut the ends off so I settled on these and a 3 Dorman/8" quick disconnect for the return line, which I also replaced with 350psi rubber hose and wrapped both hoses in spiral wrap.
