1920 has a leak in another place

Check it: Small hole in carb leaks gas when acc. pump is cycled and a slow weep at idle. does this mean a accelerator pump seal is bad or check ball? Squirts out like a pump shooter when cycled. more so on the return stroke. DANGEROUS leak, can not run like this and it has be mobile by Thursday. Help me A-Body - wan, your my only hope!
hole is at base of pump casting corner of bowl and body right at the corner, see it? black
