Volvo Penta OEM Gasket — Part No. 3580378
Part Number: 3580378
Brand: Volvo Penta
Official Product Type: Gaskets, Seals & O-Rings

Diagram Position: Confirm via Volvo Penta parts diagram for your engine serial — associated with MD2020 fuel system regulation group
This is a genuine Volvo Penta OEM gasket used in the fuel system regulation assembly of selected Volvo Penta marine diesel engines. Gaskets in this assembly provide the sealing interface between fuel system components — the material, thickness, and compression characteristics are specific to the Volvo Penta application. Using a generic substitute risks improper sealing, fuel leaks, or component damage.
Compatible Applications
- Volvo Penta MD2020 series — fuel system regulation assembly (strongest verified reference based on part number sequence)
- Other Volvo Penta marine diesel applications where Part No. 3580378 is specified
- Confirm fitment using your engine model and serial number against the Volvo Penta parts diagram before ordering
Serial Number Requirement
Gasket fitment varies by engine family, assembly version, and serial number range. Always verify Part No. 3580378 against your engine serial number and the applicable Volvo Penta parts diagram before ordering. Gaskets that appear similar can have different material grades or compression thicknesses that affect sealing performance.
Dimensions & Weight
- Estimated Weight: Approximately 0.02 kg
- Exact dimensions (OD, ID, thickness): confirm via Volvo Penta parts diagram for your engine serial
Supersession
Order using Part No. 3580378 as the active number. If a supersession exists for your engine serial, it will appear in the official Volvo Penta parts lookup. No confirmed replacement part number has been identified in current catalog data.
Service Interval
Replace this gasket any time the sealed joint is opened during service. Gaskets are single-use components — reusing a compressed gasket is a leading cause of post-service leaks. Replace as part of any fuel system regulation assembly service, or whenever the mating surfaces are separated for inspection or repair.
Installation Notes
Clean all mating surfaces thoroughly before installation, removing all traces of the old gasket material. Inspect surfaces for warping, scoring, or corrosion. Apply sealant only if specified in the Volvo Penta service manual for this joint. Torque fasteners to the specified value in the correct sequence. Never reuse this gasket once it has been compressed.

Technical FAQ
Can I reuse this gasket if it looks undamaged?
No. Once a gasket has been compressed under torque, its sealing properties are permanently altered. Even if it looks intact, reusing it significantly increases the risk of a post-service leak. Always install a new gasket when reassembling.
Do I need sealant with this gasket?
Only if specified in the Volvo Penta service manual for this particular joint. Many OEM gaskets are designed to seal without additional sealant — applying it when not required can actually interfere with proper compression and cause leaks.
How do I confirm this is the right gasket for my engine?
Use your engine model and serial number to locate the correct Volvo Penta parts diagram for the fuel system regulation assembly. Match the part number at the gasket position to 3580378 before ordering.
Parts Desk Insights
The most common issue we see with gaskets in this assembly is post-service leaks caused by reusing the original gasket — it’s a very easy shortcut to take when the old gasket looks fine, but it almost always leads to a callback. The other frequent situation is customers ordering a gasket by appearance or by measuring the old one, which doesn’t account for material grade or compression thickness. Best used as a direct OEM replacement any time this joint is opened — it’s a low-cost part relative to the labour involved in a repeat repair.
