FAQ
Will the A7SABF592 support mild performance upgrades?
Yes. The DF-165-5G supplies 165 GPH, which is ideal for stock to moderately modified 7.3L trucks (tunes, intake/exhaust, light injector upgrades).
Does it replace the factory frame-rail pump?
Yes. It mounts on the frame using the included sandwich plate and connects to the factory suction and feed lines for a clean install.
What maintenance is required?
Replace the fuel filter (e.g., FF100-2) and the water separator (WS100) at the intervals recommended by AirDog or sooner in harsh conditions.
Is there a kit for newer Power Stroke engines?
Yes. See A7SABF593 (6.0L), A7SABF594 (6.4L), A7SABF589 (2011–2016 6.7L), and A7SABF590 (2017–2023 6.7L).
