FAQ
Will this work with my tuned or higher-hp Duramax?
Yes. The A4SPBC188 supports many tuned builds with its 150 GPH flow and consistent low-side pressure, helping protect injectors and the CP3 by reducing aeration.
Does it replace the CP3 injection pump?
No. This system supplies clean, de-aerated fuel to the factory (or upgraded) CP3 for improved reliability and performance.
Is drilling the tank required?
Most installs use the included draw-straw solution and OE-style quick connects. See the install manual for the method used on your model year.
What about warranty and MAP pricing?
AirDog enforces MAP and related warranty rules. Always purchase through authorized channels and keep proof of purchase.
