Volvo Penta 23021428 – Low-Pressure Electric Fuel Pump
Part Number: 23021428
Brand: Volvo Penta
Official Product Type: Low-Pressure Electric Fuel Pump
System: Fuel Supply – Carbureted Gasoline Marine Engines
Quantity Per Assembly: 1
Overview
The Volvo Penta 23021428 is a genuine OEM low-pressure electric fuel pump designed for carbureted Volvo Penta gasoline marine engines. It supplies fuel from the boat’s fuel system to the engine’s carburetor and is the current replacement for several earlier Volvo Penta electric fuel pump part numbers, including 3858261 and 856955. This is a low-pressure carbureted application pump — it is not interchangeable with the high-pressure fuel pumps used on Volvo Penta fuel-injected (EFI) engines.

- Insufficient fuel delivery to the carburetor
- Hard starting or failure to start
- Engine hesitation or loss of power under load
- Intermittent pump operation
- Electrical pump failure confirmed by testing
- Fuel leakage from the pump body or connections
Before replacing the pump, also inspect the fuel filter, wiring, relay, fuel lines, and tank supply to rule out other causes.
Installation Notes
Disconnect battery power and relieve fuel-system pressure before beginning service. Inspect fuel hoses, electrical connections, and all sealing components during installation. Lubricate new O-rings with clean fuel before assembly and check for leaks after returning the engine to service.
Parts Desk Insights
Best use case: Replacing a failed or weak electric fuel pump on a carbureted Volvo Penta 4.3L, 5.0L, or 5.7L GL or GS gasoline engine. This is one of the more common fuel system service items on these engines. Common issue: Customers sometimes order this pump for fuel-injected Volvo Penta engines — the 23021428 is a low-pressure carbureted pump only and is not compatible with EFI applications. Always confirm the engine is carbureted and verify the model and serial number before purchasing.
