Good Maintenance Practices:

  • Running your vehicle with a near empty fuel tank can cause your pump to fail. For longevity, maintain proper fuel levels.
  • Fuel contamination is one of the top reasons for fuel pump failure. For proper operation and longevity, it is critical to have a clean fuel system.
  • When servicing an electric fuel pump, always replace the strainer, and inspect the inline fuel filter for contamination.
  • When replacing a fuel pump, check for proper electrical connections, pressure, volume, and current.
  • Make a service appointment if your vehicle shows any of the following symptoms: 'Service Engine Soon' light is illuminated, improper engine idling, hesitation, or stalling, excessive exhaust smoke, abnormal engine noises, or noticeable fuel odors.
  • Refer to your Vehicle Owner's manual for additional vehicle maintenance practices.
