BMW 5 Series/7 Series Older Model Fuel Pump Core 16141183178 (DK-071), horizontal tube design, direct replacement

When BMW 5-series (E39) or 7-series (E38) old models show startup difficulty, acceleration weakness, rough idle or sudden stall while driving, this typically indicates fuel pump core aging. This pump core pressurizes fuel from the tank to the engine to maintain proper mixture; if pressure is insufficient or fuel supply interrupted, faults occur. This product is a direct OEM replacement with OEM number 16141183178 (DK-071) horizontal-pipe design; fits BMW 525, 728 and other older horizontal-pipe fuel pump assemblies; also compatible with 16141183389, 16141182109, and other part numbers. Installation requires disconnecting battery negative, ensure pump seal intact, and check hoses for leaks to prevent oil pressure issues.
