FAQ
Q: 1.Which engine models and truck applications is the FS53048 / FS53048NN fuel water separator compatible with?
A: The FS53048 / FS53048NN fuel water separator is engineered primarily for heavy-duty Cummins X-Series engines (X12, X13, X14) and select QSK / ISZ / ISX industrial platforms equipped with high-pressure common rail (HPCR) fuel systems. It is widely used in heavy-duty trucks such as Foton Auman, FAW Jiefang, Shacman, and DFCV Dongfeng trucks, as well as various generator sets and construction equipment.
Q: 2. What is the primary function and filtration rating of this fuel water separator?
A: The FS53048NN serves as a primary fuel filter (pre-filter) designed to protect sensitive fuel injectors and high-pressure pumps. Utilizing advanced NanoNet® media technology, it delivers:
Filtration Efficiency: 5-micron rating for ultra-fine particle removal.
Water Separation: Over 95% efficiency in removing both emulsified and free water from diesel fuel.
Q: 3. What are the primary OE part numbers and cross-reference numbers for FS53048 / FS53048NN?
A:This filter replaces or interchanges with several major OEM and aftermarket part numbers, including:
Cummins OE Part Numbers: 5308719, 530871900, 5444245
Fuel Processor Assembly Base: Fleetguard FH21442 / FH21442NN
Donaldson: P551057, P551058
Mann-Filter: WK 11 026 / WK 11026 z
Baldwin: PF46142
WIX: WF10442
Q: 4. Is the FS53048NN filter suitable for high-sulfur or low-quality diesel fuel in export markets?
A: Yes. The advanced NanoNet® composite media used in the FS53048NN provides superior structural stability and dirt-holding capacity, preventing early clogging even under tough working conditions, inconsistent fuel quality, or high-humidity tropical climates.
Q: 5. Which secondary fuel filter should be paired with the FS53048 / FS53048NN?
A: For optimal fuel system protection on Cummins X12/X13 platforms, it is strongly recommended to pair the FS53048NN (Primary Water Separator) with the Fleetguard FF5782NN or FF5825NN (Secondary High-Efficiency Fuel Filter).
Q: 6. Do you supply genuine Fleetguard, OEM quality, or high-performance aftermarket options?
