Fuel Heater Kit by BD Diesel

If you’ve ever tried to start your diesel truck on a frigid morning only to be met with hesitation—or worse, nothing at all—you know just how frustrating fuel gelling can be. That’s where the BD Diesel Flow-Max 12V 320W Fuel Heater Kit comes in. Designed to combat one of diesel’s biggest cold weather challenges, this kit keeps fuel flowing freely so your engine starts reliably, even when the temps drop into the deep negatives. What makes this kit really stand out is its 320-watt self-regulating heater element, which delivers over three times the heating power of typical single-element systems. It installs directly between the BD Flow-Max filter head and water separator, making it an incredibly efficient spot to warm the fuel before it hits the injection system. By heating the fuel right at the filter, you help prevent it from thickening or turning to gel in the lines, which is often the root cause of hard-start or no-start issues during cold snaps.

Hassle-Free Install

Installation is as straightforward as it gets. The kit comes with a pre-made wiring harness and sealed electrical connectors, so there’s no splicing, guessing, or hacking your factory wiring. It’s built for a clean, plug-and-play install that any DIYer with basic tools can knock out in no time. If you rely on your truck in the winter—whether it’s for work, hauling, or just getting to where you need to go—this heater kit adds an extra layer of protection that can make a world of difference.
