It should also be replaced if the original gasket is torn, compressed, fuel-soaked, hardened, leaking, stuck to the mounting surface, or damaged during removal. A poor fuel pump gasket seal can contribute to fuel seepage, fuel odor, hard starting, poor fuel delivery, or repeat service issues after pump installation.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eInstallation Notes\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eClean both mating surfaces before installing the new gasket. Remove old gasket material carefully without gouging aluminum or machined sealing faces. Confirm the fuel pump mounting surface is flat, the fasteners are clean, and the correct fuel pump is being installed for the engine serial number. Install the gasket according to the Mercury service manual for the specific engine, and avoid adding silicone or non-approved sealants unless the service procedure specifically calls for them.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eAlternate\/Superseded Part Numbers\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e27-8M0108647\u003c\/strong\u003e — current Mercury\/MerCruiser formatted service part number\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e8M0108647\u003c\/strong\u003e — current manufacturer part number\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e27-431861\u003c\/strong\u003e — earlier Mercury\/MerCruiser formatted part number\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e431861\u003c\/strong\u003e — earlier manufacturer\/base part number\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e27-43186 1\u003c\/strong\u003e — alternate printed\/catalog spacing reference\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003eParts Desk Insight\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eFuel pump gaskets should be replaced any time the pump is removed because old gasket material often compresses, tears, or sticks to the block during disassembly.
