1125030-H01A0 is consistently identified as a fuel-water separator filter element and is co-listed with FS53052NN. Exact-number records point to Dongfeng Tianlong flagship KX and related heavy-duty applications, but equipment serial coverage and the complete separator-head configuration are not manufacturer-verified. No current exact owned product image is published, so this page remains Probable/noindex. Confirm both numbers, thread, dimensions, valve and drain arrangement, water sensor interface, engine model and vehicle serial.
