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.\u003c\/p\u003e\n\u003ch4\u003eHassle-Free Install\u003c\/h4\u003e\n\u003cp\u003eInstallation is as straightforward as it gets.

When this happens, there's not a whole lot you can do to prevent the gelled fuel from injecting into the engine, which causes enough problems down the road. FASS has the fix to this with their Electric Heater Kit that was designed to prevent fuel from gelling while driving during extremely cold temperatures. Your FASS Fuel System has 2 ports for electric heaters, which makes installation for this kit a breeze. The heaters begin warming once you turn your ignition on, and will automatically shut off after the proper temperature has been reached.

The H\u0026amp;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\u0026amp;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.\u003c\/p\u003e\n\u003ch4\u003eIntegrated Drain Port\u003c\/h4\u003e\n\u003cp\u003eOne 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFits:\u003c\/strong\u003e 2017, 2018, 2019, 2020, 2021, 2022, 2023, 2024 GM Silverado\/Sierra 2500HD\/3500HD 6.6L Duramax\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFits 2017–2024 GM Silverado\/Sierra 2500HD and 3500HD with 6.6L Duramax engine.\u003c\/li\u003e\n\u003cli\u003eReplaces the factory plastic fuel filter housing with a CNC-machined billet aluminum version.\u003c\/li\u003e\n\u003cli\u003eDesigned for a direct bolt-on install using factory hardware, no modifications required.\u003c\/li\u003e\n\u003cli\u003eMaintains compatibility with OEM-style fuel filters for easy servicing.\u003c\/li\u003e\n\u003cli\u003eFar more durable than stock, ideal for harsh climates, high mileage, or work use.\u003c\/li\u003e\n\u003cli\u003eHelps eliminate common failures like cracking, leaking, or broken fittings.\u003c\/li\u003e\n\u003cli\u003eIncludes an integrated drain port for cleaner, simpler fuel filter changes.\u003c\/li\u003e\n\u003cli\u003eImproves both reliability and appearance with a high-quality anodized finish.\u003c\/li\u003e\n\u003cli\u003eGreat upgrade for preventative maintenance or while servicing the fuel system.\u003c\/li\u003e\n\u003cli\u003eInstalls in minutes and immediately upgrades a known weak point in the L5P fuel system.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"H\u0026S Motorsports","offers":[{"title":"Default Title","offer_id":49527213883676,"sku":"HSM134001","price":129.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0738\/2279\/8108\/files\/134001_1.jpg?v=1722345867"},{"product_id":"17-22-gm-2500-3500hd-66l-duramax-l5p-fleece-replacement-fuel-injector-connector","title":"Fleece FPE-HAR-L5P-INJ-PT-4P Replacement Fuel Injector Connector 4-Pack | 2011-2024 GM Silverado\/Sierra 2500HD\/3500HD 6.6L Duramax","description":"\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eIncludes four connectors with 4.5\" pigtails\u003c\/li\u003e\n\u003cli\u003eIdeal replacement during injector service\u003c\/li\u003e\n\u003cli\u003eFixes common injector circuit DTCs\u003c\/li\u003e\n\u003cli\u003eReplaces GM part number 19368140\u003c\/li\u003e\n\u003cli\u003eIncludes heat-sealable butt connectors\u003c\/li\u003e\n\u003cli\u003eReduces resistance and electrical issues\u003c\/li\u003e\n\u003cli\u003ePrecision-cut and crimped in-house\u003c\/li\u003e\n\u003cli\u003eCompatible with LML, L5P, LM2, and LZ0\u003c\/li\u003e\n\u003cli\u003eClean, OE-style fit and finish\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eHigh-Quality Injector Connector Kit with Pigtails\u003c\/h4\u003e\n\u003cp\u003eIf you’ve ever tracked down an injector trouble code on your Duramax, especially one that just won’t go away, you might’ve found the issue wasn’t the injector at all.

Whether you’re doing a full injector swap or just cleaning up a rough-running truck, this kit gives you the peace of mind that comes with brand-new, high-quality connections. This set includes four replacement connectors, each with a 4.5-inch pigtail, making it ideal for partial repairs or when you’ve got just a few that need attention. Over time, these connectors can develop resistance from heat and vibration, leading to poor injector performance or persistent codes like P0201 through P0208. Replacing them early helps avoid misfires, erratic idle, or worse, an injector circuit failure that leaves you sidelined.\u003c\/p\u003e\n\u003ch4\u003eHigh-Quality Construction \u0026amp; Design\u003c\/h4\u003e\n\u003cp\u003eEach pigtail is produced in-house by Fleece, using fully automated wire cutting and terminal crimping to ensure consistency and factory-quality fitment.

The included heat-sealable butt connectors make the job quick and clean, sealing out moisture and preventing corrosion from creeping in later.

Designed for universal use across diesel platforms like Cummins, Duramax, and Powerstroke, this sump kit offers a cleaner, more efficient way to draw and return fuel, all without the need to drop your tank. What makes this kit especially user-friendly is its single-bolt mounting system. Instead of wrestling with multiple bolts or time-consuming brackets, all it takes is one hole and one fastener. That means less time under the truck and more time doing what matters, getting it back on the road. Once installed, the sump pulls fuel from the lowest point in the tank, giving your system consistent, uninterrupted flow, even when you're down to the last few gallons. No more fuel starvation when you're climbing steep grades or braking hard with a heavy load behind you.\u003c\/p\u003e\n\u003ch4\u003eComplete Kit with High-Quality Hardware\u003c\/h4\u003e\n\u003cp\u003eThis kit also features 1\/2-inch NPT ports for both suction and return, making it ideal for high-volume fuel systems like the FASS Titanium Signature Series.

It's a small addition that plays a big role in maintaining performance and drivability under stress. Durability is another strong point.
