85 120hp Evinrude Fuel Pump

[Luna Sea]

Looking through the Seloc manual. All it says is "fuel pumps covered in this manual are the throw away type". Think I'm going to order the Clymers manual. Checked all hose clamps and fittings already. So the hose that comes out of the top of this pump and goes under it and forward to...? Does anyone know what this does and/or what it is attached to? Can't get my hand under there to get at that clamp and fitting definately floats/moves when I move the hose. Thanks.

Mike, If its not the gas in or the gas out then its the hose for the pulse that moves the diaphram that pumps the gas.You need to be sure you get a good strong pulse of gas from the line to the carb.Be careful gas fumes are heavy and can travel across a floor or down stairs or lay in the bottom of a boat.Not sure what your problem is but if you have a strong flow of gas to the carb and you have a problem with stumbling stalling or bogging then it may be time for a carb rebuild.

Thanks Steelspike. Posted earlier about primer bulb not staying full. And engine bogs at high rpm but not if someone keeps squeezing that bulb. So we're thinking fuel pump. But it sure don't look like the throw away kind they show in my manual.
