Are you trying to tell us that your stuff looks like this?  One prong is for fuel, second prong is for latching, third prong serves no other function than to prevent attaching hose connector backwards.  OMC hose assemblies made for many years all fit.

John, If you have a Paint program on your computer you can use it to resize your pic and “save as” your pic as a Jpeg and you can put it in a post. A pic may show you have a merc/yam fitting instead of an OMC….mercury has a motor side fitting and a tank fitting that has a tank built in so it can’t be switched I believe. Like everyone has been saying OMC’s single line fittings haven’t changed in decades.

A few years ago I forgot to pack the hose for my 1968 Evinrude 9.5  I stopped halfway there at my brother’s place but he did not have a spare so I bought one half way to our destination.  The tank side fit as expected but the motor side connector had an extra casting bump that prevented it the latch from “clicking” on.  Since I wasn’t close to where I bought it, i used a pocket knife to scrape away the bump.  It worked fine and does not leak.  I figured if there was a problem I would buy another fitting locally.

Frank R, Dan, Wek:    Yes, those pictures show the fittings.  (For some reason the pic I took was sized at 13.4 MB so I can’t send it.) I basically did what Wek suggested except I used a Dremel tool to grind the plastic on the new fuel line fittings so they would attach to the motor and tank. Once I get the motor put back together, I will run it using the “doctored” fuel line and see if it leaks or not. Thanks for all the help & ideas.

I’d be surprised if somebody didn’t ask.  There is a screw retainer plate inside the tank which prevents dumping the last bit of gas out when turning the tank upside down.  Removing the drain screw opens a bypass path allowing that last bit of gas to exit.  Can’t say that I’ve ever used the feature that much.  There are other ways to get the gas out.
