FUEL FILTER = P550737 OR P550736

A heavy-duty, metal canister-style fuel filter cartridge designed for diesel fuel/water separator assemblies, most commonly the Davco Elemax 382. It captures dirt, rust, and water from the fuel before it reaches the engine, protecting the fuel injection system. This filter is rated at 50 microns, making it a primary filtration element that is typically replaced during routine service or when the Davco separator shows a restricted filter. It can be used as a direct replacement for Donaldson P550737 (7 micron) or P550736 (25 micron) elements, though the micron rating differs, so it is often used as a primary filter where the assembly calls for a 50-micron media.
