FAQ
Q: Will this fit my Cat 320DL?
A: The 320DL typically uses a different fuel filter configuration. This 322-3154 is designed for the D2 and E-series excavators. Check your operator's manual or contact us with your machine serial number for verification.
Q: How often should I drain the water separator?
A: Check the water-in-fuel (WIF) sensor daily. Drain any accumulated water immediately. Even small amounts of water can damage common rail injectors — the #1 cause of Cat fuel system failure.
Q: Can I use this on Cat generators?
A: Only if your generator set uses the same C4.4/C6.6/C7.1 engine platform and filter head. Always verify by part number cross-reference before ordering.
