Merc 115 L6 middle carb pours gas when I pump fuel bulb

[tomconnolly]

While rebuilding my engine, I removed the carbs. Now when I pump the fuel line bulb, gas pours out the middle carb from behind the air butterfly. The bulb isn't pumping up hard, and the other carbs aren't dumping gas like the middle one. I checked the float bowl assy, and it's correctly set up. What else could I check?

The float or float valve needs attention.

Turned out it was apparently the wrong fuel pump rebuild kit. Didn't mention I also did that rebuild. One of the diaphragms had two 3/8" holes in it where the original didn't. We'll see how she does when I fire it up tomorrow evening...

A Mercury dealer would not normally supply the wrong parts.
