Free returns on all eligible orders
You have 30 days to request a return. All sale items are final sale.
The Volvo Penta Injection Pump 3834308 is a genuine Volvo Penta diesel fuel injection pump reference for engines whose fuel-system parts diagram calls for 3834308. Volvo Penta catalog cross-reference data shows 3834308 superseded to 3841399, with 3841399 shown as the updated injection pump number.
This is a high-value, calibrated fuel-system component, not a visual-match part. On large Volvo Penta mechanical diesel engines, the injection pump works with the governor, fuel rack, timing gear/coupling, injection pipes, and nozzles to meter and deliver fuel at the correct timing and volume. Volvo Penta D34A MS/MT documentation identifies these engines as direct-injection, 12-cylinder, 4-stroke V-engines with a fuel injection system, governor, fuel feed pump, and fuel injection pump as core engine-side components.
Key Features
- Genuine Volvo Penta diesel injection pump reference
- Original part number: 3834308
- Updated / replacement reference: 3841399
- Used in the engine fuel injection system where the Volvo Penta parts diagram specifies this pump
- Must be matched by engine serial number, pump tag, governor setup, and pump calibration
- Dealer catalog data shows 3841399 as no longer available from the manufacturer in current references, making serial and availability checks important before sale.
Engine Compatibility
Use this injection pump only where the Volvo Penta engine parts diagram confirms 3834308 or the updated reference 3841399.
This style of injection pump should be treated as configuration-specific. Fitment can depend on:
- Engine model and serial number
- Rated rpm and output
- Pump calibration
- Governor type and linkage arrangement
- Existing pump identification tag
- Fuel-system diagram version
Do not match this pump by appearance alone.
Serial Number Fitment Notice
Confirm the engine serial number, existing injection pump tag, and Volvo Penta fuel-system diagram before ordering. Volvo Penta documentation also notes that engine identification numbers should be used as the reference when ordering service and spare parts.
When This Part Needs Replacement
Replace the injection pump only after proper fuel-system diagnosis confirms pump-related failure. Common reasons for replacement include internal pump wear, fuel leakage, sticking or poor rack movement, incorrect fuel delivery, timing/calibration issues, hard starting, uneven running, excessive smoke, poor throttle response, or loss of rated power.
Installation Notes
Installation should be handled by a qualified diesel fuel-injection technician. The pump must be timed, installed, bled, and checked according to the Volvo Penta service procedure for the exact engine. During installation, inspect the governor linkage, fuel rack movement, feed pump, fuel filters, injection pipes, sealing washers, overflow/return components, and fuel control linkage. Volvo Penta fuel-system guidance highlights bleeding the injection pump, checking injection timing, and verifying fuel control operation as part of fuel-system service.

Parts Desk Insight
Injection pumps are one of the parts where the tag matters more than the shape. Two pumps can look nearly identical but have different calibration, governor setup, or engine-rating requirements. Match the serial number and pump identification before ordering to avoid an expensive wrong-fit return.
