Fuel Heater Kit for Aftermarket Fuel Systems

When winter hits hard, the last thing you want is fuel gelling up and leaving you stranded. That’s where the BD Diesel 12V 320W Flow-MaX Fuel Heater Kit steps in. Designed for cold weather diesel owners who don’t let freezing temps slow them down, this compact, high-powered heater keeps your fuel flowing clean and consistent—even in subzero conditions. What makes this kit stand out is the self-regulating 320-watt PTC heating element. It doesn’t just warm things up—it delivers over three times the heating power of most single-element systems, and it does it more efficiently. That extra heat means better protection during brutal cold starts, fewer fuel-related issues, and less downtime when you need your truck to be ready no matter what the weather’s doing.

Simple Install

Installation is straightforward and quick. The unit sandwiches right between your water separator or pre-filter and the filter head, which means there’s no need for complicated plumbing or custom brackets. BD includes a pre-made wiring harness with sealed connectors, making the electrical side of the job just as easy. It’s plug-and-play, and you’re back on the road in no time. This kit is a direct replacement for the FASS HK-1001 and fits the FASS FS-1001 water separator filter. It’s also universally compatible with BD Flow-MaX, AirDog, and FASS fuel systems, so it’s a great upgrade whether you're running a BD setup or something different. It’s built with everyday reliability in mind but performs like something you'd expect on a purpose-built cold weather rig.
