FAQs

Will 100 GPH support my goals?
Yes. TSPD02100G is rated for stock to ~600 HP on 1989–1993 5.9L Cummins. Step up to TSPD02165G (165 GPH) if you plan 600–900 HP. 

What filters should I run?
Use PF3001 (particulate) + XWS3002 (water separator), or the XL pair PF3001XL + XWS-3002-XL for extended service intervals. 

How loud is the pump?
The PLUS uses FASS Whisper Technology for very quiet operation while maintaining rated flow. 

Is it truly bolt-on?
Yes. The kit includes bolt-on bracketry that reuses factory bed bolts; cab-and-chassis may require minor modification.
