FAQ
Q: Is 165 GPH right for my build?
A: TSPC10165G is ideal for 600–1000 HP Duramax builds (LB7–LMM). For stock-600 HP trucks, see TSPC10100G. For bigger turbos/injectors targeting 900–1500 HP, consider TSPC10250G or TSPC10290G listed above.
Q: How loud is the pump?
A: The Plus series uses FASS Whisper Technology to significantly reduce noise versus prior designs while maintaining flow.
Q: Do I still need the factory filter housing?
A: The system provides 2-micron filtration with water separation and air/vapor removal. Many builds delete the OE housing after proper plumbing, but follow your tuner’s guidance and verify local regulations.
Q: Will this help injector life?
A: Yes—consistent supply pressure, air/vapor separation, and fine filtration help reduce cavitation and contamination that can shorten injector life.
Q: Any cold-weather considerations?
A: The design supports cold starts, and the system provides ports for optional heaters in extreme climates.
