管路堵塞怎么引起呢一般就是尿素结晶，熄火之后管路当中的尿素没有抽干净；尿素品质不达标；不加尿素等
管路出现泄漏怎么引起呢看接头型号是否相符、密封垫出现问题、机械部分出现摩擦，造成管路泄露。
1、安装喷油泵前应对喷油泵所有零件进行清洗，
以防在安装时将脏物和杂质带入泵体内，导致零件早期磨损。同时还应注意柱塞套与油泵体配合处不能有金属屑、砂粒及棉纱纤维等杂物，以防漏油及损坏零件。
2、柱塞套切不可装反。
柱塞套一旦装反，柱塞套定位螺钉就顶住了进油孔，柱塞工作行程的进、回油只靠回油小孔，进、回油量小而且缓慢，影响发动机正常着火燃烧。
3、定位螺钉及垫片安装应符合要求：
(1)柱塞套的定位螺钉应符合要求，不可过长，否则会使柱塞套在泵体内被顶歪，影响柱塞在套内灵活运动，加速偶件磨损，还会使螺钉与回油孔间隙过小，甚至堵住回油孔，不能及时回油，造成发动机“飞车”。(2)柱塞套定位螺钉不应拧得过紧，否则会使套筒变形，卡住柱塞。其安装要求是：在未装出油阀紧座时，拧紧定位螺钉后，柱塞套在泵体内能小距离上下灵活移动，但不产生转动。(3)切不可漏装定位螺钉的铜垫片，并且要此处密封，否则会造成漏油，还会导致空气进入喷油泵，使发动机运转不稳定。
4、出油阀座的垫片不得漏装、损坏，而且要求平整：

(1)出油阀座的高压密封紫铜垫和低压密封橡胶垫，装前必须仔细检查，要求完好无损，更不得漏装，否则会造成高压油腔与低压油腔相通，致使油泵不能正常工作。(2)安装出油阀紧座时，拧紧力距必须适度。拧紧以后柱塞在柱塞套内任何位置都能灵活运动，不产生局部卡滞现象。(3)垫片必须平整。如垫片凹凸不平或有皱折，出油阀紧座拧紧后，柱塞套易单边受力，加速柱塞偶件磨损。
