Thumbnail Filmstrip of Duramax Parfit Fuel Filter Racor PFF50216 Images
Upgrade or service your 2001–2016 GM 6.6L Duramax with the Racor PFF50216 ParFit Fuel Filter. Racor (Parker Hannifin) is the OEM supplier to General Motors, and this spin-on filter meets or exceeds factory specifications while delivering superior real-world protection — especially in biodiesel blends and variable-quality diesel fuels.
Unlike cheap “will-fit” paper-pleat filters, the PFF50216 uses Racor’s advanced Aquabloc® depth coalescing media in a true dual-stage design: a primary multi-layered coalescer that captures dirt and extracts finely emulsified water, followed by a secondary polishing stage that delivers ultra-clean fuel to your high-pressure common-rail system.
Key Features & Benefits
- Superior Contaminant & Water Protection — 4-micron filtration with 99% water removal efficiency. Critical protection for injectors, high-pressure fuel pumps, and rails.
- Up to 2× Longer Service Life — Depth coalescing media lasts significantly longer than standard pleated filters, reducing maintenance costs and downtime.
- Optimized for All Diesel Fuels — Performs better than conventional filters in ultra-low sulfur diesel, biodiesel blends, and lower-quality fuels.
- Direct OE Replacement — No modifications required. Replaces GM 12633243 / 12664429 and ACDelco TP3018 / TP3012.
- Robust, Leak-Resistant Design — Unique can construction resists impact and maintains seal integrity far better than generic copies.
- Easy Spin-On Service — Quick filter changes with included O-rings.

Why Choose Racor ParFit Over Generic Alternatives? Non-OEM “will-fit” filters typically use only basic pleated paper media that struggles with emulsified water in modern diesel fuels. This leads to accelerated injector wear, corrosion, and expensive fuel system repairs. The PFF50216’s patented depth coalescing technology and precision housing deliver the proven OEM-level protection your Duramax deserves.
Pro Tip: For a complete fuel system refresh (especially if your factory filter head is leaking or aged), pair this filter with the Racor ParFit Fuel Filter Head Assembly (PFF4245R2-02).
