Just restored a 58 fat 50 JOHNSON--Came out pretty darn good.
After start up ,,as usaual,, I had an oil slick following me--it was fuel oil mix. Motor was running well on all 4.

I noticed that a 59 front crankcase half has a hose nipple (the 58 did not) on the bottom starboard side of the crankcase front half, right by the bottom bearing. I am guessing this was the 1959 "FIX" to remove unused fuel from blowing out of the bottom bearing and polluting a lake.

Question is--where would a hose go from that nipple????? I cannot see anything thing to connect it to

thanks for the help

YES-The fuel pump runs off of a hose nipple slightly higher on the front crankcase half on the port side.
Both the 58 and 59 have that connection of course. But the lower nipple on the starboard side (by the bottom bearing) only on the 59 crankcase half. Seems like that is the relief spot for the fuel collecting in the bottom of the crankcase.
But where would it go??
