项目  数量  零件  技术规格说明 
当燃油输油泵使用柴油时,燃油输油泵具有以下技术规格: 
让泵在 2940 rpm 转速下运转。 完全旁通压力应为 716 to 786 kPa (104 to 114 psi)
让泵在 840 rpm 转速下运转。 550 kPa (80 psi) 时的流量必须为 3.0 L/min (0.8 US gpm)
让泵在 2940 rpm 转速下运转。 650 kPa (94 psi) 时的流量必须为 4.5 L/min (1.19 US gpm)
封闭入口让泵在 100 rpm 转速下运转 30 秒。 泵入口至少要有 60.9 kPa (9 psi) 的吸油升程。
拧紧至扭矩为 30 ± 5 N·m (265 ± 44 lb in)。
