You are bidding on a vintage mechanical fuel pump; it is a commercial rebuilt, item # 6837; old shelf stock from a closed retailer.  It will fit several years and models; many 1963-1965 Ford & Mercury passenger cars with 6-cylinder engines, maybe others; please check your application before bidding.  Never installed but it has some surface rust from sitting for many years.  The original ragged box is included.  Although it was rebuilt sometime ago, it should be refreshed with new gaskets and rubber parts that are compatible with today's fuels.  This is a great item for someone who works with vintage fuel pumps, excellent for parts or rebuilding.  Original Ford part, not late model China junk.  Shipping is FREE for USA 48 states ONLY.
