First thing make sure all those little spings are installed correctly in the fuel pump if it is the three bolt pump. I don't think the four bolt has the little springs. Also make sure there are no holes and cracks in the line going from the pump to the crankcase. If those both check out. You may need to rig up some sort of gravity feed system to see if it will run from gravity flow. Just trying to see if we still have a carb problem, or a fuel pump problem. also make sure there are no cracks or holes in the fuel line from the tank to the carb.
