Its probably a kit they retrofitted from the superduty. You can install them on the OBS without any trouble, it just is a little more difficult than on a SD.
And it would be smart to delete the fuel bowl at the same time
Yeah the Air dog is basically the "performance" upgrade from the stock mech. lift pump and fuel bowl in the valley. Because the Air dog is a pump and filtration system all in one. Airdog and a Regulated Return would be a great E-fuel setup for an OBS (as well as an SD). Just like the custom set-ups alot of guys are running with like an Aeromotive fuel pump and an inline fuel filter. With a RR of course.
EVERYWHERE. lol Its not an easy task...but its doable...research is your best friend if you want to build your own setup...finding the pump you want to use, the filtration units you want to use, the Regulated Return set-up, and the Summit has just about evey fitting and hose you would need.
