宝马F07 535GT汽油泵总成 16117260640 高压燃油系统替换件

If your BMW F07 535i is experiencing starting difficulties, weak acceleration, rough idle, or stalling while driving, it is likely aging high-pressure fuel pump causing insufficient fuel pressure. This part, when functioning normally, pressurizes fuel from the tank to the engine injectors to ensure precise fuel-air mixture and smooth operation. This product is OEM number 16117260640, matched for BMW F07 535i (automatic). When installing, release residual fuel-system pressure first, replace the high-pressure fuel line seal, and ensure the pump-to-engine interface is clean and free of debris.
