  • •Failing lift pump
  • •Restricted fuel line
  • •Low fuel level in tank
  • •Fuel tank vent blocked

🔧 Troubleshooting Steps

  1. 1Replace fuel filters
  2. 2Check for air leaks on suction side
  3. 3Verify fuel tank has adequate fuel
  4. 4Test lift pump output pressure
  5. 5Check tank vent for blockage

❓ Frequently Asked Questions

How often should Perkins fuel filters be changed?

Perkins recommends fuel filter replacement every 250-500 hours or annually, whichever comes first. In areas with poor fuel quality, more frequent changes may be needed.

How do I bleed air from a Perkins fuel system?

Open the bleed screw on the fuel filter housing, operate the manual lift pump or electric pump until bubble-free fuel flows, then close the bleed screw. Crank engine and repeat if needed.
