❓ Quick FAQ

Which FASS pumps is this bundle for?
Aftermarket FASS Titanium, Titanium Signature, and Platinum Series lift pumps across Cummins, Power Stroke, and Duramax platforms. Not backward-compatible with older 95 Series units.

Why different micron ratings, and which side goes where?
The XWS-3002 (20-micron) mounts on the suction side to strip water and larger debris before the pump. The PF-3001 (2-micron) mounts on the pressure side as a final fine filter protecting the injection pump and injectors.

How do I swap these filters?

1. Place a catch pan under the pump and pull the FASS fuse to disable it.
2. Unscrew both old filters with a strap wrench and drain them.
3. Clean the mounting studs and confirm old gaskets came off.
4. Pre-fill the PF-3001 with diesel (not the XWS-3002); lubricate both seals.
5. Hand-thread the new filters on, then tighten an additional 3/4–1 turn.
6. Re-fuse the system, cycle the ignition to prime it, then check for leaks before driving.
