  Service Life of Cummins Fuel Pumps

  The service life of a Cummins fuel pump can generally reach over 200,000 kilometers without requiring maintenance. However, many factors can affect its lifespan.

  First, fuel quality is crucial. If the fuel is not clean, impurities can cause severe wear or seizure of the distribution rotor. Therefore, it is important to use fuel that meets standards and is clean—for example, No. 0 light diesel in summer and -10 light diesel in winter. Before adding fuel to the tank, it should be allowed to settle for at least 72 hours.

  Second, the lead seals should not be removed arbitrarily, such as those on the fuel adjustment screw or the maximum speed limit screw. Unauthorized removal may void warranty claims and can alter engine performance.

  Third, the air filter element must be replaced regularly. Clean it every 4,000 km and replace the element every 24,000 km. In harsh working environments, these intervals should be shortened.

  Additionally, it is important to drain any water from the fuel system. After the engine has run for 500 hours or 16,000 km, the special dual-stage fuel filter should be replaced, and the fuel-water separator alarm switch should be checked frequently.

  Finally, avoid pouring cold water on a hot pump head, as rapid cooling can cause material contraction and lead to plunger seizure.

  In summary, paying attention to these factors can extend the service life of a Cummins fuel pump, ensuring it continues to serve the vehicle reliably.
