雪佛兰科鲁兹1.4T高压燃油泵 12682079 12649461 原装位

If your Chevrolet Cruze 1.4T has acceleration weakness, rough idle, hard starting, or engine light on, this is usually due to aging internal seals or piston wear in the high-pressure fuel pump causing insufficient fuel pressure. This high-pressure pump pressurizes fuel from low pressure to high pressure (about 10-15 MPa) and injects precisely into the cylinder to ensure power and combustion efficiency. OEM numbers 12682079/12649461; fits Buick and Chevrolet Cruze 1.4T (post-2000 models). When installing, clean the pump mounting surface and replace the seal; torque bolts to standard torque (about 25 N·m) to avoid deformation or leaks.
