FAQ
What horsepower range is TSPC12165G designed to support?It’s targeted for 600–1000 HP LML Duramax builds and delivers 165 GPH to keep rail supply stable under load.
How does the Titanium Signature Series Plus differ from the standard Titanium Signature Series?
The “Plus” adds upgrades like ORB fittings, black-anodized 6061 hardware, black fuel line, and refined internals while keeping 2-micron filtration, air/vapor separation, and MFR polishing.
Is a sump required for installation?
No. This kit is designed for a clean bolt-on install using factory bed bolts. If you want an even simpler no-tank-drop approach, consider the FASS “No-Drop” Series Plus kits listed above.
What maintenance intervals should I expect?
FASS suggests filter service around 30,000 miles under normal use. Keep fresh PF3001/XWS3002 filters on hand or grab the FLP3000 pack linked above.
