FAQ
Q: Is 165 GPH enough for a tuned 6.7L Cummins?
A: Yes—TSPD12165G is rated for 600–1000 HP builds, making it ideal for tuned street trucks within that range.
Q: Which way do the new-style filters mount?
A: With current-gen filters, install PF3001 (particulate) on the suction side and XWS3002 (extreme water separator) on the pressure side. For XL, pair PF3001XL with XWS3002XL.
Q: Do I need a sump?
A: Not required, but many high-demand builds add the FASS STK5500B sump/suction tube to cure 1/4-tank starvation and stabilize supply under heavy load.
Q: Will this void my warranty?
A: The system itself carries a limited lifetime warranty (with registration). Vehicle warranty impacts vary by dealer/policy; keep install documentation and follow FASS guidelines.
