FAQs
Do I need to drop the fuel tank to install this?
No. The included sump allows a “no-drop” installation, saving significant time.
Is this overkill for a lightly modified truck?
Yes—240 GPH is intended for 900–1200 HP builds. For milder setups, consider the NDTSC15180F140G (140 GPH) or NDTSC15250F220G (220 GPH).
Which filters does this system use?
Use PF3001XL (particulate) and XWS-3002-XL (water separator) — or the appropriate filter pack for updated Titanium Signature systems.
Do I need a heater for winter?
Heater kits are optional but recommended in extreme cold. The pump is heater-ready.
