I turns out that I have the CAP system and only one engine filter that's a fuel/water separator. The additional filter behind the condenser may have been stock or an upgrade. Either way, it's also a fuel/water seperator. The biggest take away is DO NOT believe the manual when it says don't prime the filters. I had a "no start" all morning even though I followed the procedures. Finally, I removed the filters, filled them with Deisal fuel, cycled the key twice and it started right up....LESSON LEARNED!
