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.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eGenuine Volvo Penta diesel injection pump reference\u003c\/li\u003e\n\u003cli\u003eOriginal part number: \u003cstrong\u003e3834308\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eUpdated \/ replacement reference: \u003cstrong\u003e3841399\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eUsed in the engine fuel injection system where the Volvo Penta parts diagram specifies this pump\u003c\/li\u003e\n\u003cli\u003eMust be matched by engine serial number, pump tag, governor setup, and pump calibration\u003c\/li\u003e\n\u003cli\u003eDealer catalog data shows \u003cstrong\u003e3841399\u003c\/strong\u003e as no longer available from the manufacturer in current references, making serial and availability checks important before sale.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003eEngine Compatibility\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eUse this injection pump only where the Volvo Penta engine parts diagram confirms \u003cstrong\u003e3834308\u003c\/strong\u003e or the updated reference \u003cstrong\u003e3841399\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eThis style of injection pump should be treated as configuration-specific.

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fuel control operation as part of fuel-system service.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eAlternate\/Superseded Part Numbers\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eVolvo Penta 3834308\u003c\/strong\u003e — original injection pump reference\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVolvo Penta 3841399\u003c\/strong\u003e — replacement \/ updated injection pump reference\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003eParts Desk Insight\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eInjection pumps are one of the parts where the tag matters more than the shape.
