Monaco Windsor RV with 8.3L Cummins CAPS

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!

The engine seems to idle more smoothly and quieter. No leaks at all. I want to say hats off to you guys for putting together such a complete kit as well as instruction manual.

We do all of our own installations at our shop in Kimbolton, Ohio. In terms of throttle response and engine idle, we have noticed better pick up and better pulls on the hills. We track fuel mileage and have had about 0.5 mpg increase. We have also noticed longer time period between filter changes and better start up in cold weather.

2000 American Eagle 8.3 Cummins Engine

I installed the AirDog system myself on a motorhome. I have noticed a smoother engine idle, improvement in fuel mileage, reduced engine start time, downshift further up on hills than before, and top the hill at higher speeds. I have a tendency to stop at the same fuel stops when repeating our trips from the previous year. I have completed two different trips, both in excess of 1,200 miles. At each stop, I noticed that it was taking fewer gallons to fill. When I returned home, I compared my receipts to the previous year and confirmed this to be correct. Also, crank time when starting the engine has reduced, so it takes less time for the engine to start. Another improvement is hill climbing – on long grades, I have noticed I get further up before the automatic transmission is downshifting to a lower gear and I top the hill at higher speeds. I think it is also important to note that I would not have purchased this system had it not been for the information and assistance provided by your tech support.

The system makes a huge difference in starting the truck. It starts up instantly above freezing and still starts down to 20 degrees without the engine block heater or ether, which was not the case previously. I installed the AirDog myself and have noticed an improvement in throttle response and smoother engine idle. In general, I think the former military vehicle owner community could really benefit from your 24V product! I recommend the system to everyone I encounter with starting/fuel line issues. It makes a huge difference starting in all conditions.

Complete system and easy to install – I installed myself. Very complete and professional wiring harness. After installing the AirDog, there is definitely a smoother idle and seems to start easier.

2010 Cummins ISX 550 HP

The last three years of operating my 2010 550 hp ISX with a FASS, my average economy was 7.2. I was hoping to have some fuel increase from switching to the AirDog, but couldn’t imagine the actual gains I was going to receive. My fuel economy with the AirDog has jumped to 8.5-9.1, plus the filter monitor separator. Way to go AirDog!

Has had AirDog on trucks with great success for 12+ years. After installing the AirDog, there has been an increase in fuel economy from 4.5-4.8 mpg to 5.4-5.8 mpg, as well as a reduction in usage of about 10%.

1993 KW with Cummins N14

1993 KW with Cummins N14

I have been in the trucking industry for over 20 years and currently operate a 1993 KW with a N14. My runs are coast to coast in Canada at 118,000 lbs and the 48 states loaded at 80,000 lbs with an average mpg of 5.5. (With the AirDog), it now is 6.0 mpg and gained 25 hp. The engine runs smoother and great acceleration! If you enjoy top performance or think you’ve forgotten what performance was, then AirDog is the way to go!
