奔驰100老款燃油泵总成 6614703294 4插 上海汇众品质替代

Fuel pump assembly designed for Mercedes-Benz 100 series (1990-1995) with 2.0L-2.6L displacement and Shanghai Hise models with 4-pin connector. This fuel pump assembly delivers fuel from the tank to the engine, ensuring a stable low-pressure fuel supply system. OEM number 6614703294 (cross-check MC0000009280), using Shanghai Hise quality alternative, pressure and voltage are standard specifications. Replacement difficulty is medium; disconnect the battery negative and relieve fuel pressure first; during installation, pay attention to the orientation of the 4-pin connector and the sealing ring. For B2B buyers, this is an original-equivalent solution with about 30% cost savings versus OEM, and Hise quality offers solid durability, suitable for bulk purchase for older Mercedes maintenance.
