Fuel System - Inspect
将燃油输送到发动机的部件若有问题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。 油管必须没有阻塞和与规格不符的弯折。 检验回油管有无皱缩。
- 安装新燃油滤清器。
- 利用 175-7546 机油滤清器切割器 切开用过的滤清器。 检查滤清器有无过多杂质。 确定杂质的源头。 进行必要的修理。
- 保养燃油粗滤器(如有配备)。
- 操作手动注油泵（如有配备）。 如果感觉到阻力不稳定，测试燃油中的空气。 更多有关信息资料，请参阅测试与调整, "燃油中的空气 - 测试"。
- 排除燃油系统内的空气。 请参阅测试与调整, "燃油系统 - 预注"。
