I have a 35 HP Eninrude outboard that runs great, but just quits running occasionaly for no reason. I have to squeeze the primer bulb (it loses pressure) until it is hard, and the motor will run great. it is almost like it runs out of gas. Doesn't do it all the time, but just enough to be annoying. I checked the fuel lines , no leaks. When I open the gas tank, there is a loud burp (tank is pressurized). I was going to try replacing the primer bulb, but does anyone have any suggestions first? Is this a sign of a bad fuel pump? How would I diagnose this?<br />Thanks!
