Description:

Part Number: 0149-2583
Condition: New
Manufacture/Brand: Cummins

Fits 0149-2583 For Cummins 12V fuel systems on compatible Onan generator applications

Purpose of using 0149-2583:

 
  • Supply fuel to the engine – moves gasoline or diesel from the tank toward the engine.
  • Maintain fuel pressure – provides the pressure needed for proper fuel injection.
  • Ensure consistent fuel flow – supplies the engine with enough fuel during starting, idling, acceleration, and heavy loads.
  • Support fuel injection – allows fuel injectors to receive fuel at the correct pressure.
  • Improve engine starting – builds fuel pressure before or during engine startup.
  • Support proper engine performance – helps maintain the correct air-fuel mixture and stable engine operation.


Signs of a Bad Electric Fuel Pump 0149-2583:

  • Engine Hard Starting – The engine takes longer than normal to start or requires multiple attempts.
  • Engine Stalling – The engine may suddenly shut off, especially during acceleration or at higher speeds.
  • Loss of Power – The vehicle may hesitate or lose power when accelerating, climbing hills, or carrying a heavy load.
  • Engine Misfires – Insufficient or inconsistent fuel pressure can cause rough running and misfires.
  • Low or No Fuel Pressure – The pump may fail to provide the pressure required by the fuel system.
  • Whining or Humming Noise – An unusually loud whining sound from the fuel tank can indicate a worn pump.
  • Engine Surging – The vehicle may accelerate unevenly because fuel pressure is fluctuating.
  • Poor Fuel Economy – An inefficient or malfunctioning pump can contribute to abnormal fuel consumption.
  • No-Start Condition – If the pump completely fails, the engine may crank but not start.
  • Check Engine Light – Fuel-pressure or fuel-delivery problems can trigger diagnostic trouble codes and illuminate the check-engine light.
