Which fuel filters work with H&S Motorsports conversion kits?

Our CAT and Baldwin filters are designed to work with H&S Motorsports fuel filter conversion kits. Be sure to match the correct part number listed on your kit’s product page.

What’s the difference between a fuel filter and a fuel/water separator?

A standard fuel filter removes particulates and contaminants from diesel fuel. A fuel/water separator also removes moisture, protecting injectors and pumps from water damage.

Do I need the billet housing or isolator sleeve with these filters?

If you're running an H&S Motorsports fuel filter conversion kit, the billet housing and isolator sleeve are required for proper fitment and sealing. These components are included in complete kits or can be purchased separately for replacement.

How often should I replace my fuel filter?

We recommend replacing fuel filters every 10,000–15,000 miles, or as specified by your vehicle’s maintenance schedule—especially in high-demand or off-road conditions.
