Serial Number Note: Mercury application listings show this regulator across selected 0M-, 0W-, and 1A-series engines. Confirm the exact engine serial number and fuel-system configuration before ordering — Mercury used different regulator arrangements across production periods, particularly on 496 MAG and 8.1L engines. Match to the Gen III fuel cooler / fuel module, not by displacement alone.

Parts Desk Insights
The most important detail with 892681 is that it is a fuel pressure regulator, not a voltage regulator — the product was previously mislabelled as "REGULATOR" in the system. It belongs specifically to the MerCruiser Gen III Cool Fuel module 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. For a complete fuel module service, also consider the Gen III Cool Fuel Filter Kit 35-13523 and Fuel Module Kit 8M0047215.
