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 3803679 is a genuine Volvo Penta diesel fuel injection pump reference for TD73E industrial diesel applications. Volvo Penta reman/exchange catalog data lists TD73E with injector pump number 3803679, and parts catalog references show earlier injection pump number 477648 replaced by 3803679.
This is a calibrated mechanical fuel-system component. It should be matched by engine model, engine serial number, existing pump identification tag, and the Volvo Penta fuel-system diagram before ordering.
Key Features
- Genuine Volvo Penta diesel injection pump reference
- Current part number: 3803679
- Replaces earlier Volvo Penta injection pump reference 477648
- Confirmed Volvo Penta reman/exchange application: TD73E
- Used in the engine fuel injection system
- Related pump-tag reference associated with old Volvo number 477648: Denso 191000-9230 / ND-PE6NB120C320RND923; confirm by the pump plate before using as a cross-reference.
Engine Compatibility
Confirmed application reference:
- Volvo Penta TD73E — injector pump / injection pump reference 3803679
This pump should not be treated as a universal TD7 / TD73-series pump. Related engines such as TD73ES, TD730ME, TAD730V, and other 7-litre Volvo Penta industrial variants are listed with different injector pump numbers in the Volvo Penta reman/exchange catalog.
Serial Number Fitment Notice
Confirm the engine serial number, existing pump tag, governor setup, pump manufacturer number, and Volvo Penta fuel-system diagram before ordering. Injection pumps can vary by engine rating, governor arrangement, calibration, and serial range even when the engine family looks similar.
When This Part Needs Replacement
Replace the injection pump when a qualified diesel fuel-system technician confirms pump-related failure, internal wear, leakage, poor fuel delivery, sticking rack movement, incorrect timing or calibration, hard starting, uneven running, excessive smoke, poor throttle response, or loss of rated power.
Installation Notes
Installation should be handled by a qualified diesel injection specialist. Correct pump timing, fuel-line sealing, governor linkage setup, rack movement, fuel bleeding, and calibration checks are critical. Inspect the fuel filters, feed supply, return/overflow components, injector lines, sealing washers, throttle/governor linkage, and injectors during service.
Alternate/Superseded Part Numbers
- Volvo Penta 3803679 — current injection pump reference
- Volvo Penta 477648 — earlier injection pump number replaced by 3803679
- Denso 191000-9230 — related pump manufacturer reference associated with Volvo 477648
- ND-PE6NB120C320RND923 — related pump type reference associated with Volvo 477648
Parts Desk Insight
The clean match on this one is TD73E + 3803679, with 477648 as the older number. The pump tag should still be checked before sale, especially because similar Volvo TD73-family engines can use different pump numbers and calibration setups.
