Airdog II
The new AirDog® II Demand Flow Fuel Preporator®
This new model Fuel Preporator® improves on the original by offering demand flow, so that the unit only draws as much fuel from the tank – through the tank module – as is required by the engine, and then returns only air and a dribble of fuel to the tank. What does this mean? Connecting to the tank module means there is no need to drill holes in the fuel tank to install an aftermarket fuel draw straw, so installation with the included fittings is QUICK and EASY. The AirDog II also features either a preset or adjustable stainless steel pressure regulator. As always, all AirDog® II units come complete with fittings, fuel lines, mounting brackets, and full-color installation manual specific to each model truck.

so what if you want to upgrade from an original airdog and already have an aftermarket draw straw? can you use it or you need to plug the hole? I personally dont need to upgrade, just putting it out there for reference i guess.
From what I have been told you can still use for aftermarket Draw Straw.
