FAQ
Will this 290GPH system work on a daily-driven Duramax?
Yes—while sized for high-hp builds, it delivers exceptionally clean, air-free fuel and steady pressure that benefits street trucks too. Size your system to your current or planned power level.
What’s different about the PLUS vs. standard Titanium Signature Series?
PLUS kits include ORB ports, black-anodized 6061 fittings, and black line for cleaner installs and improved sealing versus NPT-threaded ports.
Do I need a sump or to drop the tank?
This kit installs conventionally. If you want the easiest routing and to avoid dropping the tank, see the No-Drop Series Plus kits (e.g., NDTSPC10290G) linked above.
What maintenance do the filters require?
Plan on ~30,000-mile intervals under normal conditions. Shorten intervals for severe service or contaminated fuel.
