the air dog returns it's fuel back to the filler neck which makes it difficult to run the dual tanks b/c u r trying to run the return fuel line from the engine which goes through the selector valve to figure which tank it goes back to, but the air dog return will only go back to a single tank so what happens if you fill up and your not on the tank with the air dog return running to it??most would switch to a single tank if they wanted to run the air dog pump. personally i run a regulated return with a stock SD pump, but i don't feel that the SD pump flows enough fuel to go bigger than 200cc injectors. there are bigger pumps that we can put in place of the SD pump in a reg return system as well. i would do regulated return if it was me.
