FAQ
Will this 100 GPH pump support mild tuning on my 6.4L?
Yes—RP-4G-100 is ideal for stock to mild setups. For higher fuel demand, consider the 150 GPH version (R4SBF221).
Do I need to run a return line?
No. The Raptor-4G is internally regulated and does not require a return line for this application.
What pressure is it set to from the factory?
Approximately 8–10 PSI. The regulator is adjustable for fine-tuning as needed.
Is the kit complete, or do I need additional fittings?
The kit includes quick-connect fittings, line, harness, and hardware for a clean, professional install (see manual).
What if I want a full air/fuel separation system instead of just a lift pump?
Step up to a complete AirDog system such as A4SPBF073 FP-150-4G or the latest A7SPBF266 II-5G DF-100-5G.
