FAQ
Will this work on a stock 2019–2023 Cummins?Yes. It’s compatible with stock trucks and provides cleaner, de-aerated fuel. It also supports future performance upgrades.
Does it replace or work with the factory filter housing?
The FP-150-4G feeds the factory fuel filter housing on these trucks; it does not delete it. You’ll still service the OEM filter along with AirDog’s pre- and final-stage filters.
What filters does it use and how often should I change them?
Use WS100 water separator and either FF100-2 (2µ) or FF100-10 (10µ) depending on your setup. Inspect every oil change and replace at the first sign of restriction/contamination or per AirDog guidance.
Do I have to drop the tank to install this?
No tank drop is typically required. The kit includes a draw-straw and frame-rail mounting hardware; follow the official manual linked above.
Is 150 GPH too much for a lightly-modified truck?
It’s fine for stock to moderately-modified trucks. If you prefer a lower-flow option, consider FP-100-4G (A4SPBD106).
