Signs You Need a Replacement
If your equipment is showing any of these symptoms, the injection pump may be the cause:
- Engine cranks but won’t start — The pump may have lost prime or stopped delivering fuel. Check for fuel at the filter outlet before replacing the pump.
- Stalling under load — A weak pump can’t maintain pressure at high demand. The engine runs fine at idle but dies when you put it to work.
- Fuel pressure warning (if equipped) — Modern equipment monitors fuel rail pressure. A low-pressure warning often means the pump is failing.
- Loud whining from fuel system — A failing pump makes a high-pitched whine that gets louder as it warms up. Normal pump noise is a low hum.
- Air in fuel lines — If you see bubbles in the transparent fuel line or the primer bulb won’t stay firm, the pump may be drawing air through a worn seal.
- Excessive return flow — Too much fuel returning to the tank instead of reaching the injectors indicates internal pump wear.
Before You Replace the Pump
Before replacing the pump, check the fuel filter and fuel lines for restrictions. A blocked filter causes the same symptoms as a failing pump on equipment. When installing the new pump, fill it with clean fuel before connecting the lines — this reduces priming time and prevents dry-run damage. After installation, bleed the system fully and check for leaks at all connection points. Replace the fuel filter at the same time as the pump to protect the new unit from debris.
Frequently Asked Questions
Will this fit my Mercedes OM924.920?

Can I cross-reference 0414799027 with 230-280?
Yes. Both 0414799027 and 230-280 are interchangeable OEM numbers for this part. They refer to the same component with the same specifications, just different part number revisions.
How do I check if my engine code (OM924, OM906, OM904, OM926) matches?
The engine code is stamped on a metal tag attached to the engine block, usually near the timing belt cover or on the cylinder head. Compare the code you find with the list above. Engine codes are 3 to 6 characters long.
My vehicle is a 1998 model – is it covered?
The compatibility range for this part includes 1998-2004. The 1998 model year falls within this range, but verify the engine code and body type match. Mid-year production changes sometimes mean two vehicles from the same model year use different parts.
