Re: Replacement fuel pump for a 1966 33hp Evinrude?
If it bolts to the intake port with no air hose running to it, then pretty much any of that style "large" pump will work with the same set-up. Used on 20hp to 75hp motors from the 1970s on up...
If it bolts on the exhaust cover, has a glass sediment bowl and has an air line running from the intake port cover, then any of the fuel pumps of that style (casting #377113) will work...
