  Common Issues with Cummins PT Fuel Pumps and How to Fix Them

  The Cummins PT fuel pump is known for durability, but like any mechanical fuel system, it may develop issues over time due to wear, fuel contamination, or improper adjustment. Understanding common symptoms can help prevent downtime and costly repairs.

  Typical Symptoms of PT Fuel Pump Problems:

  Hard Starting or Failure to Start
  Often caused by air in the fuel line or insufficient fuel pressure.

  Black Exhaust Smoke
  Indicates excessive fuel delivery; check the pump adjustment and injectors.

  Engine Power Loss
  Could be due to clogged fuel filters or a weakened pump plunger.

  Fuel Leakage
  Usually related to worn seals or aging gaskets.

  Maintenance Tips:

  l Use clean, high-quality diesel to prevent internal wear.

  l Replace fuel filters regularly to avoid contamination.

  l Perform periodic pressure and flow tests.

  l Ensure correct PT pump timing when servicing.

  When replacement is needed, avoid cheap aftermarket pumps with unknown quality. JOZ, an authorized Cummins parts distributor, offers genuine PT fuel pumps and rebuild kits to keep your engine running reliably.
