奔驰高压燃油泵 A2700700501 A270070401 0261520238 0261520211 高性能替换件

Is your Mercedes or VW Skoda experiencing weak acceleration, hard starting, idle jitter, or engine fault light? These symptoms often indicate wear of the internal plunger or seals in the high-pressure fuel pump, causing insufficient fuel pressure. In normal operation, the pump pressurizes low-pressure fuel to high pressure to ensure precise spray atomization at injectors, maintaining efficient combustion and power output. This replacement part fits OEM numbers: A2700700501, A270070401, 0261520238, 0261520211, for Mercedes-Benz and VW/Skoda produced after 2000. Before installation, thoroughly clean fuel passages, replace seals, and tighten to specified torque to avoid foreign matter entering and damaging the pump.
