Troubleshooting & FAQ
How do I know if this gasket will fit my engine?
This gasket is designed for Volvo Penta models 150S-D, 150SR-D, and D42A. The best way to ensure a correct fit is to match your original part number to one of the cross-references listed in our Part Number Matrix, such as 957175, 957174, or 48588.
Where exactly is this gasket installed?
This is a fuel system gasket. In the Volvo Penta D42A engine schematic, it is identified as part number 75. For other models, its precise location may vary. We recommend consulting your engine’s official service manual for a diagram.
What are the signs of a failing fuel system gasket?
Common symptoms include a strong smell of gasoline or diesel, visible fuel leaks or seepage around component joints, poor engine performance, hesitation, or difficulty starting. A visual inspection of the old gasket might reveal cracking, brittleness, or compression failure.
Does this gasket require any sealant during installation?
Most gaskets of this type are designed to be installed dry. Applying additional sealant can sometimes interfere with proper sealing or cause excess material to enter the fuel system. Always follow the installation guidelines in your engine's service manual.
