Frequently Asked Questions

Is 28526888 a genuine Delphi fuel injection pump?

Yes. 28526888 is a Delphi high pressure common rail fuel injection pump used in selected Bobcat and Doosan D18/D24 diesel applications.

What engines does Delphi 28526888 fit?

It is listed for D18 1.8L and D24 2.4L engines, including G2 D18 and G2 D24 versions.

Is 9109-936A related to this pump?

Yes. Delphi 9109-936A is a related fuel metering valve / IMV / SCV used in all listed Delphi 28526888 common rail fuel pump applications.

Should the machine be diagnosed before replacing the pump?

Yes. Low rail pressure, hard starting or no-start symptoms can also be caused by injectors, metering valve, rail pressure sensor, fuel contamination or electrical faults. Professional diagnostics are recommended.

Is professional installation recommended?

Yes. Common rail fuel system components require clean handling, correct installation and proper diagnostic procedures.

Can installed parts be returned?

No, unless a verified warranty case applies. Confirm compatibility before installation.

Common Symptoms of Fuel Injection Pump Failure

Hard starting, long cranking, engine no-start condition, unstable idle, rough running, loss of power, low rail pressure, poor acceleration, black smoke, abnormal engine noise, sudden stalling or check engine light may indicate a problem in the diesel common rail fuel system.

These symptoms are not exclusive to the high-pressure pump. They may also be caused by injectors, fuel metering valve, rail pressure sensor, fuel pressure regulator, contaminated diesel, blocked fuel filter, air in the fuel system, wiring faults or ECU control problems. Professional diagnostics are recommended before replacing the fuel injection pump.

Important Diagnostic and Installation Information

Before replacing the diesel fuel injection pump, a professional inspection should be performed, including fuel pressure testing, fuel supply inspection, injector condition testing, fuel contamination inspection, fuel filter inspection, fuel line inspection and diesel fuel quality analysis.

If the previous injection pump failed due to contamination or internal wear, the injectors, fuel tank, fuel lines, fuel filter housing and related fuel system components should also be inspected and cleaned before installing the replacement pump.

Installing a new diesel injection pump into a contaminated fuel system may result in repeat failure and additional diesel system damage.
