Re: 1994 88hp evinrude
Check for obstructions in the fuel system, from the tank to the bulb. Check for a plugged fuel tank vent; or a bad anti-siphon valve. If you have a portable gas tank available, try it that way and see if you have the problem.<br /><br />The bulb itself could have a bad check valve in it, if you haven't already tried replacing it.
