FYI: According to the Old Outboard Handbook, in 1957, Evinrude made an 18 HP, not 15 HP. 1956 and earlier were 15 HP. That looks like a nice, pristine motor!
The fuel connector O-rings can sometimes be pried out with a small screwdriver while you hold the spring-loaded center post in with another small screwdriver or rod, but if they are really old, they may have gotten too hard to deform with the screwdriver and pry out. If so, you need to whack a small rod through from the hose nipples to press out the round, flat pieces that you see on the surface and the O-rings are behind these. If you can get the O-rings out without pressing the retaining plates out, squeeze the new ones on each side so you have a long, narrow thing and feed them back into the hole, while still holding the spring-loaded post in and prod/pry it into place with a small screwdriver.
