I have a 97 evinrude 115 E115eleua. Does anyone know of a way to diagnose whether I have a bad vapor pump? I have a fuel issue and don't have vacuum gauge or pressure tester that I own to see if I have a bad fuel pump or not. I replaced it last year, and up until the end of march the fuel system has been good. At work we were able to determine that the fuel pump is pulling adequate amount of fuel from the tank, but then we hooked up a gauge to the starboard fuel manifold, and the motor was not getting enough fuel. So I've rebuilt some of the fuel bracket components.Put new fuel bracket on, new vst cover, new o ring on vapor pump, new o rings for both hoses that lead to either fuel manifolds, new o ring on this 90 degree nipple on the back of the fuel bracket. Does anyone know how to test to see if I have a bad vapor pump? The fuel pump was replaced last year, the vapor pump is the original 97 model vapor pump that the motor has always had.. so I'm guessing this might be the culprit? I read somewhere that you could possibly pull the vent line on it and see if you can run it long enough before it starts dumping raw fuel. The post stated if it doesn't act up then you the vapor pump is bad.
