Air Dog vs. Regulated Return
I know the air dog is a pump and filter set up. The regulated return, from Diesel Innovations, has no filtering but still says it ups the pressure to 65-75psi. Which is better? They are both around $500. The air dog 2 replaces the whole fuel system, but is $660. Is this really gonna help as much they claim?
