FAQs
What power level is the DF-100-5G (100 GPH) best for?Ideal for stock to mildly modified 2015–2016 LMLs that need stable supply and better filtration without over-fueling return flow.
Does this kit replace the factory in-tank pump?
LML trucks do not include a factory lift pump; this system adds a frame-mounted supply pump and filtration while using the factory module for suction/return.
Do I need tuning after installing the AirDog II-5G?
No tuning is required. The system supplies cleaner, deaerated fuel at consistent pressure to the factory injection pump.
How often should I change the filters?
Follow AirDog’s maintenance intervals and adjust based on fuel quality/use. Inspect more frequently in harsh or contaminated fuel conditions.
