Thanks in advance ,really appreciate all the answers ive recieved in the little time i have been here!

That is the bowl vent. It keeps the gas in the bowl at atsmopheric pressure so that delivery is constant.

If it were not there, pressure within the bowl would vary with fuel pump fluctuations and air demands. The gas/air ratio would then change from the desired 14-16 to 1 ratio.
