It should also be replaced if there is fuel seepage, fuel smell near the cooler, pressure loss, hard starting after fuel-system service, a flattened seal profile, cracking, swelling, cuts, or visible damage. Fuel-system seals should not be reused once compressed or disturbed.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eInstallation Notes\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eRelieve fuel-system pressure before service and follow the Mercury service manual procedure for the exact engine. Clean the sealing groove and mating surfaces before installation, and inspect the fuel cooler body, cover, fittings, fasteners, hoses, and related seals while the assembly is apart. Do not substitute a generic O-ring, as the correct seal profile and material are important for fuel-system sealing. After reassembly, check carefully for leaks before returning the engine to service.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eAlternate\/Superseded Part Numbers\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e26-8M0214975\u003c\/strong\u003e — current Mercury\/MerCruiser formatted service part number\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e8M0214975\u003c\/strong\u003e — current short part number\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e26-863151\u003c\/strong\u003e — earlier Mercury\/MerCruiser reference\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e863151\u003c\/strong\u003e — earlier short part number\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003eParts Desk Insight\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eFuel cooler seals are small, but they should be treated as one-time service seals.
