The Volvo Penta Injection Pump 3581917 is a diesel fuel injection pump used in the KAD32P / KAD32P-A fuel system. Volvo Penta parts diagrams show 3581917 at diagram position 1 in the Fuel System group, with earlier injection pump 3581451 replaced by 3581917. This pump meters and delivers fuel to the injectors and must be matched by engine model, serial number, pump tag, and the Volvo Penta fuel-system diagram before ordering.

Use this pump where the Volvo Penta fuel-system diagram calls for 3581917 or where older pump 3581451 has been superseded to 3581917. Do not assume interchange with KAD43, KAD44, KAMD43, KAMD44, KAD300, or KAMD300 injection pumps without checking the exact diagram and pump tag, even though those models appear in the broader catalog family.
Serial Number Fitment Notice
Injection pump fitment is calibration-sensitive. Confirm the engine serial number, existing pump identification plate, injector setup, fuel-system diagram, and any service history before ordering. The same fuel-system diagram also shows injector and delivery-pipe variants, so matching the full fuel-system configuration matters.
When This Part Needs Replacement
Replace the injection pump when a qualified diesel technician confirms pump-related failure such as poor fuel delivery, hard starting, uneven idle, excessive smoke, fuel leakage, loss of rated power, poor throttle response, internal wear, or calibration failure. Fuel filters, feed pump, injectors, fuel supply, return lines, and timing should be checked before replacing the pump.
Installation Notes
Installation should be performed by a qualified diesel fuel-injection technician. Correct pump timing, clean fuel-line handling, feed pump condition, injector line routing, rack/governor operation, sealing washers, and system bleeding are critical. Inspect related diagram parts during service, especially feed pump 3582310, gasket 3501530, O-ring 968971, fuel filter 840531, delivery pipes 3581763–3581766, return line 3581450, and injector references used for the specific engine build.
Alternate/Superseded Part Numbers

Parts Desk Insight
The clean match on this pump is KAD32P / KAD32P-A + 3581917, with 3581451 as the older number. The pump tag still matters, because injection pump calibration and the surrounding injector/delivery-pipe setup need to match the exact engine build.
