Product Description
Airdog A4SPBC190 FP-100-4G is a 100 GPH original AirDog system engineered for the 2015–2016 Chevy/GMC Duramax 6.6L LML. It mounts on the frame bracket ahead of the fuel tank, draws through the factory suction port, feeds clean, de-aerated fuel to the CP4 injection pump, and returns separated air/vapor to the tank via a filler-neck tee—improving idle quality, reducing cavitation, and helping pump longevity.

FAQs
Is 100 GPH enough for tuned daily drivers on LML?
Yes. FP-100-4G supports typical street builds on the LML. For higher demand or future power goals, consider the FP-150-4G (A4SPBC191) or II-5G options above.
Does this replace my factory low-pressure supply setup?
Yes—this AirDog mounts to the frame, uses the OE suction port, and feeds the CP4 directly with clean, de-aerated fuel.
Do I need to drop the tank for install?
No. The kit uses the factory suction port and returns air/vapor to the tank via the included filler-neck tee as described in the manual.
What filters does the kit use and how often should I change them?
It uses AirDog spin-on fuel and water separator filters. Follow the maintenance intervals in the install manual and adjust for fuel quality and use.
