Re: 1959 Evinrude 18HP Golden Jubilee Fuel Line Conversion Help

Well, I would begin by saying if you want to run both engines off the same tank, I would use the heavier 24:1 mix that the 18hp requires even in the newer engine. The conversion for this engine is fairly simple, simply using the pieces off a 1960 18hp. You will need just two parts, the fuel pump and a new bypass cover with the fuel pump mount and pulse port:

Items 39,40, and 7, and #0 the fuel pump
Yes, I too am confused, this indicates a new fuel pump is no longer available, but I find that hard to believe, look for #388685 fuel pump

You will also need item 111, the single line fuel inlet connector. YES, I realize this is way over priced, I am sure you can find a used one.
The only other thing you will need to do is cap off the pressure port outlet nipple on the intake manifold. You can put a rubber cap over the nipple, or remove the nipple and thread in a convention threaded cap. I’m not sure what size thread is used, but think it is pipe thread.
The fuel pump will have a screen filter, so you can delete the filter on the engine to simplify things, or keep it in the line as well….
