FAQs

Does this 100 GPH “Plus” system support mild performance upgrades?
Yes. It’s rated for stock up to roughly 600 HP when paired with healthy injectors and tuning. For larger injectors/turbos, consider the 165 GPH (TSPD08165G) or 250 GPH (TSPD08250G) systems listed above.

What filters does this kit use?
Current-gen systems use PF3001 (particulate, suction side) and XWS3002 (extreme water separator, pressure side). We stock both, as well as the FLP3000 six-pack.

Is it noisy?
FASS Whisper Technology significantly reduces pump noise. Most customers report a quiet, OEM-like sound profile after install.

Will it help injector life?
Yes. Air/vapor separation + 2-micron filtration help reduce fuel-related injector failures common on these trucks.
