FAQ
What’s the difference between TSPC11165G (PLUS) and TSC11165G?The Plus kit includes hardware and routing updates (ORB fittings, updated lines) and is designed to pair with the latest PF3001/XWS3002 filters for improved serviceability. If you don’t need the Plus updates, see the standard kit here: TSC11165G.
Which filters should I run with this system?
Use the updated pair: PF3001 (particulate) + XWS3002 (water separator). For extended service intervals, choose PF3001XL + XWS3002XL.
Is drilling the tank required?
This kit installs conventionally; for a simplified “no-drop” sump-style install, consider the NDTSPC11165G No-Drop Plus.
How often should I change filters?
FASS commonly recommends 15k–30k mile intervals depending on fuel quality and usage. For convenience, grab the combo pack here: FP3000 Filter Pack.
