It belongs specifically to the \u003cstrong\u003eMerCruiser Gen III Cool Fuel module\u003c\/strong\u003e system, so the first fitment check is always confirming the engine has a Gen III fuel cooler, not just matching displacement. The most common ordering issue is customers on 496 MAG or 8.1L engines where Mercury used different fuel system configurations across serial ranges. Always verify the serial number and confirm the Gen III fuel module is present before selling.
