Fuel Water Separator With Fitting Assembly OE 1125005-H02B1 for Dongfeng GX & KX Heavy Trucks

This genuine fuel water separator with fitting assembly OE number 1125005-H02B1 is factory original fuel pre-filter component exclusively matched for Dongfeng GX and KX heavy-duty trucks. It separates condensed water and intercepts solid contaminants inside diesel fuel before fuel enters high-pressure fuel pump and injectors. The main body adopts high-strength die-cast aluminum alloy with anti-corrosion coating. Equipped with multi-layer hydrophobic composite filter media for excellent water-oil separation efficiency. Impact-resistant transparent PC water bowl allows visual observation of accumulated water, with drain outlet for regular water discharge. Complete original matching connectors, wiring harness and mounting brackets are pre-assembled, perfectly matching Dongfeng GX/KX chassis pipeline layout for direct installation. This separator strictly passes DFCV OEM filtration efficiency test, low-temperature anti-cracking test and diesel corrosion resistance test. Authorized third-party fuel component inspection verifies port thread, fitting specification and mounting dimension fully consistent with factory original assemblies, widely used as full replacement spare parts for clogged filters, cracked bowls and aging separators on Dongfeng GX & KX long-haul fleets.

PRODUCT DESCRIPTION

Pre-Assembled OEM Fittings, Transparent PC Water Bowl, High Efficiency Hydrophobic Filter

This OE 1125005-H02B1 fuel water separator comes complete with original matching pipeline connectors, wiring harness and mounting accessories, eliminating separate procurement of adapters during maintenance. The thick transparent PC water storage bowl resists impact and low-temperature cracking, enabling maintenance staff to observe water level without disassembly. Internal multi-layer hydrophobic composite filter paper effectively separates emulsified water and tiny particulate contaminants in diesel, preventing water corrosion and abrasive wear on precision fuel injectors. The aluminum main housing features full anti-rust treatment to resist long-term erosion from diesel, mud and rainwater on chassis. All fuel inlet and outlet interfaces adopt CNC precision machining, fully consistent with original vehicle pipeline specifications, supporting plug-and-play whole-unit replacement without cutting fuel hoses.

Need Separate Fittings Purchase, Opaque Bowl Hard To Monitor Water, Low Efficiency Filter Damage Injectors

Heavy truck fuel system maintenance technicians often encounter many troubles from inferior aftermarket separators: fittings are not included, requiring additional purchase and on-site modification; opaque housing cannot observe water accumulation, excessive water enters fuel system and causes injector rust and sticking; ordinary filter paper has poor water separation effect, impurities easily pass through and wear fuel pump, leading to insufficient engine power. This genuine DFCV OEM fuel water separator completely eliminates these hidden risks: complete pre-assembled fittings save installation time; transparent bowl real-time monitors water volume; high-performance filter fully purifies diesel, reducing fuel system overhaul frequency for Dongfeng GX & KX fleets.

DFCV OEM GX/KX Fuel System Standard, Multi-Round Filtration, Low-Temp & Corrosion Lab Testing

As core pre-filter safety component of Dongfeng GX & KX heavy truck diesel fuel supply system, this 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 printed OE serial number are attached on original carton for genuine product traceability, all bracket hole spacing, fuel port thread and fitting specifications strictly follow original vehicle factory engineering drawings, zero assembly mismatch after replacement for all Dongfeng GX and KX heavy truck models.
