Fuel System - Inspect
将燃油输送到发动机的部件若有故障就会造成燃油压力低。 这会使发动机性能降低。
- 检查燃油箱中的燃油油位。 确保油箱盖的通气孔没有被灰尘阻塞。
- 检查燃油管有无泄漏。 燃油管必须没有阻塞和与规格不符的弯折。 确认回油管无皱缩。
- 安装新燃油滤清器。
- 使用 175-7546 机油滤清器切割机总成切开用过的滤清器。 检查滤清器有无过多污染物。 确定污染物的来源。 进行必要的修理。
- 保养燃油粗滤器（如有配备）。
- 如有必要，测试燃油内是否有空气。 有关更多信息，请参阅测试和调整, "燃油内有空气 - 测试"。
- 排除燃油系统内可能存在的所有空气。 请参阅测试和调整, "燃油系统 - 注油"。
