Billet Fuel Filter Housing for 6.6L Duramax

If you’ve ever looked at the plastic fuel filter housing on your L5P Duramax and thought, 'That doesn’t belong on a heavy-duty truck,' you’re not alone. The H&S Motorsports Billet Fuel Filter Housing is built to solve exactly that problem. Designed as a direct replacement for all 2017–2024 6.6L Duramax engines, this housing upgrades one of the factory system’s weakest links with a much stronger, much better-looking solution. H&S took the factory design and gave it a serious durability boost by CNC-machining the housing from solid billet aluminum. It still fits like the stock part and accepts the factory filter, but the construction is in a whole different league. This upgrade is perfect for truck owners who are tired of dealing with cracked or leaking plastic housings, especially in harsh climates or high-mileage work rigs where failure just isn’t an option.

Integrated Drain Port

One thoughtful touch is the integrated drain port, which simplifies fuel system maintenance and filter changes. You won’t be fighting with messy fuel spills or makeshift drain setups, just crack it open and let the housing do the work. The entire install takes only a few minutes and bolts up without modification, so it's an easy upgrade whether you’re doing a full service or just improving weak points as you go. But this housing doesn’t just improve durability, it also adds a clean, sharp look under the hood. The billet finish makes it feel like a proper part of a serious truck, not a throwaway piece from the parts bin. It’s a small detail, but one that shows you care about quality where it counts.
