Listed here is a NEW Mercruiser / Mercury / Quicksilver Fuel Pump Cooler Kit.  This is a Genuine OEM Mercruiser / Quicksilver / Mercury part NOT a cheap Chinese aftermarket replacement.  The part number for this kit is 8m0125852 which supersedes from part # 861156A02 (and 861156A03 to the best of my knowledge).  Only opened the box to photograph the parts inside.  All parts inside are packaged as they came from the factory.  This is the fuel pump kit that was used on many Mercruiser MPI engines starting around year 2000 up until almost present day with the GM platforms.  May be used on other engine configurations as well.  This is the pump that's located by the starboard engine mount in the plastic box on most engines.  This is for the alpha setup and some inboards NOT the bravo configuration.  Kit came off the assembly line on Feb 19, 2024 so it is not old stock that has been sitting around in a warehouse for years.  Beware of aftermarket kits disguised as OEM Mercruiser parts.  One way to tell is the factory numbers printed into the pump itself.  The number 8M0116357 and 0044al can be seen on the pump in pictures.  One is a factory part number and the other is most likely a batch number.  The parts you see pictured are the actual parts you will receive with nothing extra.  Parts are stored in a climate controlled parts room to prevent deterioration.  If you have any questions or need help with compatibility please feel free to contact me before purchasing and I will help you to the best of my abilities.  Thank you for your interest.  Steve MMSLLC :)
