It is important to consider that the injection pump is a fuel system mechanism with a complex design. It needs a delicate approach and fine-tuning. Therefore, do not try to repair the pump by yourself. Without a run-in stand, as well as without the necessary adjustment, this approach will lead to disastrous consequences. As a result, you will have to buy a new fuel pump repair kit.

The usage of a fuel pump repair kit

At significant loads of the high-pressure fuel pump, various signs appear, signaling a malfunction of the device. Among them:

1. fuel does not reach the injectors of the power unit (the plunger jams);
2. fuel flows from the pump (wear of sealing elements);
3. extraneous noise (wear of working elements);
4. broken adjustment;
5. electronics problems.

It is impossible to delay the diagnosis, as well as the repair of the high-pressure fuel pump. Proper operation of this assembly is critical for diesel engines. If repairs are not carried out in a timely manner, the cost of restoration work will increase many times over.

It should be understood that the MEAT & DORIA brand Repair Kit, fuel pump is a laborious and complex process. This will require both diagnostics, and repair, and the subsequent restoration of the performance of individual pump components, and then testing directly under load already on specialized stands.
