Help - GM power steering lines

[redfire69]

So I've installed GM performance parts serpentine kit 12497697 which includes a power steering pump with the 16MM-1.5 o-ring connector. I've got the 11/16"-18 at the steering box. I've tried twice with the Russell 6AN lines using the adapters at each end.

Each time, the Russell PS lines have leaked at the compression fittings that are supposed to be leak-proof, LOL. I'm trying Earl's PS lines tomorrow if the parts arrive. Does anyone know of a stock line I can use for this application (help, GM Gurus!)? Otherwise does anyone know of 6AN PS lines that actually work?

Thanks, Ron
