Troubleshooting & FAQ
How do I know if this gasket fits my engine?
This gasket is designed exclusively for the Volvo Penta KAD300-A model (285 HP, years 2001–2004). It corresponds to OEM part 11991 and is located at position 51 in the fuel system schematic. Please verify your engine model and part number before purchasing.
What are the signs of a failing fuel system gasket?
Symptoms of a bad gasket include a strong smell of diesel fuel, visible fuel weeping or leaking around the component, poor engine running, hesitation, or difficulty starting. Any sign of a fuel leak is a serious safety issue that should be addressed immediately.
Do I need to use sealant with this gasket?
No. This gasket is designed to create a seal on its own. Unless your official Volvo Penta service manual explicitly specifies the use of a sealant for this application, it should be installed on clean, dry surfaces.
What does "schematic position 51" mean?
This refers to the part's specific location in the official Volvo Penta service manual's exploded-view diagram for the KAD300-A fuel system. Referencing the schematic ensures you are replacing the correct component.
