I'm confused on what rebuild kit I need to purchase for my 90hp Mercury which I believe is a 1984, but may be a 1986.
Serial Number: A123634(Off the top of my head, exact number to come)

Do I need:

2.http://www.iboats.com/mall/partfind...gd_poid=112440&gd_row=50&session_id=629099169

3. http://www.iboats.com/mall/partfind...gd_poid=353828&gd_row=50&session_id=629099169

Number 2 & 3 seem to be the same replacement OEM number replacement but have a different number of gaskets. Any advise or help would be greatly appreciated.

Re: Mercury Fuel Pump Rebuild

They all look to be correct, except the Mallory has an ending serial number before your motor was made. The last two replace different OEM part numbers. You could look on the ebasicpower website and see what they recommend, see what crowleymarine website thinks the OEM Part number is or consult Mercury. I think either of the Sierra kits will work. Do you have the third large base gasket in your pump now? That looked to be the only one in question.
