Left Mount Fuel Water Separator Assembly OE 1125010-TL791 for Dongfeng GX & KX Heavy Trucks

This OE 1125010-TL791 fuel water separator adopts exclusive left-side integral cast mounting bracket perfectly matched with Dongfeng GX & KX chassis layout, no bracket modification required during replacement. The transparent thick PC water storage bowl resists impact and low-temperature cracking, enabling drivers and maintenance staff to directly check internal water level without disassembly. Internal multi-layer hydrophobic composite filter paper efficiently isolates emulsified water and tiny solid impurities in diesel, avoiding water corrosion and abrasion of precision fuel injectors. A manual drain knob is arranged at the bottom of the water bowl, users can discharge accumulated water quickly with simple rotation without removing the whole unit, greatly shortening daily maintenance time. All fuel inlet and outlet threaded ports are CNC precision machined, completely copying original truck pipeline specifications, supporting plug-and-play whole-unit replacement without cutting fuel hoses or adding adapters. The aluminum main shell with full anti-rust coating can resist long-term erosion of diesel, mud and rainwater on chassis.

Heavy truck fuel system maintenance technicians often face serious engine hidden dangers caused by inferior aftermarket fuel water separators: universal right-mount brackets cannot fit Dongfeng GX/KX left chassis reserved position, requiring cutting and welding reconstruction; opaque metal water storage cavity cannot observe water accumulation, excessive water enters fuel system and corrodes injectors; single-layer ordinary filter paper has poor hydrophobic performance, tiny impurities easily pass through and wear fuel pump core, leading to weak power and increased fuel consumption. This genuine DFCV OEM left mount fuel water separator completely eliminates these risks: dedicated left mounting bracket fits chassis perfectly; transparent bowl real-time monitors water volume; high-efficiency hydrophobic filter fully purifies diesel, reducing engine fuel system overhaul frequency and injector replacement costs for Dongfeng GX & KX fleets.

As a core pre-filter safety spare part of Dongfeng GX & KX heavy truck diesel fuel supply system, this left mount fuel water separator fully complies with Dongfeng Commercial Vehicle official heavy-duty vehicle fuel filtration component production quality standards. Every finished separator completes three mandatory professional durability laboratory tests: multi-stage diesel filtration efficiency test, -40℃ ultra-low temperature water bowl anti-cracking test, 720-hour continuous diesel soaking anti-corrosion test, maintaining stable water separation and impurity interception performance under northern cold winter, coastal high-humidity rainy weather and mountain dusty transportation environments. Anti-counterfeit QR code label and laser engraved OE serial number are attached on original carton for genuine product traceability, all bracket hole spacing, fuel port thread specification and filter paper size strictly follow original vehicle factory engineering drawings, zero assembly mismatch after replacement for all Dongfeng GX and KX heavy truck models.
