I have been chasing this for a while. I guess I am talking out loud. Every once and a while, I smell a little gas after I have parked it for a while. I have replaced every hose and gasket on the tank, new fuel lines from the tank all the way to the pump as well as a new fuel filter. How prone are these pumps to leaks? Is there a way to OHM out the pump. I never even hear the pump on to be honest. When is the pump suppposed to turn on, or is is on all the time? could it be fuct to the point where it just lets the gas pass through? I just picked up a 94 ZX9 parts bike with a pump. Could I swap the pumps and run it to see if that is the problem. I dont want to go thow parts at it unless it is a 75HP shot of juice..
