Product Description

FAQs
Will 150 GPH support my built 12-valve with larger injectors and tuning?Yes—A4SPBD103 (FP-150-4G) is sized for heavy fueling demands and maintains positive pressure to the P7100 under load.
Do I need a draw straw or sump with this kit?
For FP-150 systems, a high-flow suction tube is included and used per the instructions. Follow the install manual for routing and tank access best practices.
What fuel filters does this use and how often should I change them?
The kit uses a water separator pre-filter and a 2-micron final filter. Service intervals vary by fuel quality; inspect regularly and replace at the first sign of restriction or contamination per AirDog’s maintenance guidance.
Does it bypass the factory filter housing?
Yes—fuel is delivered directly to the P-pump with regulated pressure; see the layout in the installation manual for line routing.
