燃油泵相关的维修建议
大多数现代汽车电动燃油泵都是安装在油箱内。一些车辆访问面板看到燃油泵工作情况无需拆卸油箱就知道燃油泵好坏了。
油箱内的燃料泵要淹没在燃油里用来帮助燃料泵保持低温状态。如果燃油泵运行时暴露在空气中会很快损坏。
在更换燃油泵时燃油过滤器应该也更换新的
燃油过滤器阻塞或电气系统驱动燃油泵问题可能导致症状类似于一个有故障的燃油泵。

Related Repair Advice

• Most modern vehicles use an electric fuel pump， which is mounted inside the fuel tank. Some vehicles have an access panel that can be removed to replace the pump without having to remove the fuel tank.
• In-tank fuel pumps are submerged in fuel to help keep them cool. Running out of gas can damage the fuel pump.
• The fuel filter should always be replaced when replacing the fuel pump
• A clogged fuel filter or problems with the electrical system powering the fuel pump can result in symptoms similar to a failed fuel pump. Have the shop verify that the pump is the problem before replacing.
• Gasoline is highly flammable. When replacing the fuel pump， the battery should be disconnected and proper safety procedures followed to avoid fire and personal injury.
