I about 5 years ago I bought a 1969 Johnson Model FD-14 SeaKing 18 hp. I bought a brand new fuel tank, fuel line and primer bulb at the same time. The engine would only stay running if I kept priming the bulb. So I bought I new pump, but it look nothing like the original fuel pump. I was told the original pump was no longer available. I also bought a carb kit and installed it. The engine ran pretty good in the tank. I took the boat to the lake for the first time. It would run pretty good and just started to plane out and it would die. no presure in the prime bulb. A boat mechanic told me to adjust the float bowl an open it up a little more. I found a good deal on a Mercury motor with a electric starter, so I parked this motor after on trip to the lake.
