Listed here is ONE Mercruiser or Mercury Fuel Pump Module Cover Stainless Screw.  All available are Genuine OEM Mercruiser / Mercury parts NOT cheap Chinese aftermarket replacements.  The part number for these screws is 10-892684 and list for $32.83 each new from dealer.  Screws all have some slight normal wear/staining/scuffing consistent with parts of their age but are all fully functional.  May have some stubborn debris stuck to some threads but  all are fully operational.  This listing is for ONE SINGLE SCREW.  All available are shown in pictures.  They are made of marine grade stainless steel and a magnet will NOT stick to them.  These are the screws that hold the cover to the Fuel Vapor Separating Tank (VST) on many Mercruiser Bravo and inboard engine configurations from the early 2000s until recently.  The cover they hold part number is 892677 and supersedes to part #s 8M0086387, 8M0130861, and 8M017898 to Fuel Module Housing part # 864650A05 and supersedes to 8M0047215.  They may also be used on other pump types and other places on the engine including the possibility of Mercury outboards. These came from a 2006 5.7 MPI that was used on a freshwater Orlando chain of lakes and has never seen salt water.  May be used in other engines including outboards.  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 :)
