i have two walbro 3001 fuel pumps one is 12-69, while the tractor is running gas sprays out the little hole in the center of the fuel pump. the other is 3-76 this one sprays out a little hole on the other side of the carb. what is the problem?

It sounds to me like the gasket has a small pin hole in it allowing fuel to get to the other side and be pushed out.The hole may not be enough to keep it from running but that would be just a matter of time.I would rebuild the fuel pump or replace it.

thats a nice looking machine you have there bob. is that a stock back hoe or home made? really awesome either way.

It is a stock backhoe made by the Brantly company for the Bolens tractor.And the loader is a Johnson model 14.
