# Airdog A7SABF590 II-5G Fuel Air Separation System (165 GPH) for 2017–2021 Ford F250

**Overview:**

The AirDog II-5G for this application uses a bed bracket to be mounted inside the bed forward of the rear wheel. The fuel module is to be modified to allow the venturi fill system to work to ensure no 1/4 tank issues. The pump draws fuel from the modified fuel module and sends it to the factory frame rail feed line. The pressure line is tapped with a return y to feed the venturi in the basket with pressurized fuel. The AirDog return is sent back to the modified fuel module. This is a 165GPH (Gallon Per Hour) lift pump system for moderately modified trucks. Check out the installation manual below for a list of parts that are included in this kit.
