FAQ
How much power will the DF-165-5G support on an LML?
With 165 GPH of supply, this system comfortably supports stock to moderately tuned trucks used for towing and daily driving. For big injectors/turbos, consider the DF-220-5G linked above.
Does it replace my factory fuel filter?
No—the system works with your existing filtration. Many owners pair it with the AirDog FF100-2 and WS100 service parts listed above for maximum protection.
Is any cutting or tank dropping required?
The LML-specific kit mounts on the frame and ties into factory supply locations. Follow the official AirDog instructions linked above for routing and mounting guidance.
Will it help my CP4/CP3 live longer?
By removing entrained air and water and maintaining steady supply pressure/volume, this system reduces cavitation and helps protect high-pressure fuel components.
