• Confirm fitment using your engine model and serial number against the Volvo Penta parts diagram before ordering

Serial Number Requirement

Fitment can vary by engine family, fuel-system linkage version, and serial number range. Always verify Part No. 3580375 against your engine serial number and the applicable Volvo Penta parts diagram particularly on older diesel applications where adjacent linkage parts can appear similar but serve different regulation functions.

Technical FAQ

Can I use 3580027 or 3580261 instead of 3580375?
These numbers appear in the same diagram position in current Volvo Penta references, but interchangeability must be confirmed against your specific engine serial number and production break. Do not assume substitution without checking the Volvo Penta parts lookup for your engine.

How do I confirm this is the correct lever for my engine?
Locate your engine model and serial number, then find the MD2020 fuel system regulation diagram in the Volvo Penta parts system. The intermediate lever at Object Key 18 should show Part No. 3580375 for your serial range. If a different number appears, use that number instead.

Parts Desk Insights

This is one of those parts that looks simple but causes real diagnostic headaches when it’s worn. The most common issue we see is erratic throttle response or an engine that won’t hold a steady RPM and after checking the obvious fuel system components, the problem turns out to be a worn intermediate lever pivot that’s introducing slop into the control linkage. The other frequent situation is customers ordering by shape comparison rather than part number, which leads to the wrong lever going in because several pieces in this assembly look nearly identical. Best used as a direct OEM replacement during any MD2020 fuel system regulation service and worth inspecting the companion lock rings, washers, and springs at the same time while the assembly is apart.
