Here is what I made up for Paul K (krasuskyp on Pelican) for his 87 930.....
Photos were taken during installation. He already purchased a very reasonable priced Setrab cooler with AN fittings and I supplied the M30 hoses with my crimped "Direct-Connect" AN fittings at the cooler. The system is routed in "Series" and has worked well on both street & track.
A factory level system at a reasonable price. Perhaps Paul will chime in on his experience with this.
