FAQs
Is the DF-220-5G overkill for my truck?If you’re under ~800 HP on stock-style fueling, the DF-165-5G is usually the better match. The DF-220-5G shines on big injectors/dual-CP3 or competition setups.
Do I need to drop the tank?
No—this kit draws via the supplied straw/sump solutions and mounts to the frame. Follow the install manual for exact routing and return line connection.
What filters does it use and how often should I change them?
Use AirDog FF100-series fuel filters and WS100 water separator. Change intervals vary by fuel quality; many owners service every 10–15k miles or sooner in harsh conditions.
Will it trigger check-engine lights or fuel pressure codes?
Proper installation and regulated outlet pressure prevent issues. Monitor fuel pressure after install and consult the manual if codes appear.
