Every Stock System Needs This Upgrade!

Monaco Windsor RV with 8.3L Cummins CAPS

I installed the AirDog myself with the help from the AirDog staff on the phone! The AirDog system has fixed my problem which was downrating my engine. My RV definitely runs much better. My RV is powerful again! My SilverLeaf system is already showing a 2 mpg increase with only a couple hundred miles. I replaced my stock lift pump 3 years ago. I wish I had known more about the CAPS fuel system. I would have put the AirDog pump in at that time. Every stock system needs this upgrade!
