FAQ
What power level is this system designed to support?
The TSPC10250G flows 250 GPH and is intended for 900–1200 HP Duramax applications.
Which filters does this system use?
Use the XWS3002 water separator and PF3001 particulate filter. For extended-length options, see XWS-3002-XL and PF3001XL.
Is drilling required to mount the pump?
The included bolt-on bracket typically uses a factory bed bolt for a no-drill install; cab & chassis trucks may require modifications.
Will this help injector life on my LB7/LLY/LBZ/LMM?
Yes—by removing air/vapor and water while delivering steady pressure/volume, it reduces cavitation and helps protect injectors and the HP pump.
Do I need a sump?
Not required, but the No-Drop kit bundles this system with a sump for faster, cleaner installs.
