This makes no sense to me...there are no vent lines on the carb are there?
I know mine is a few years older but do me a favor and look down the pasenge side of the block to see if there is a nipple on the fuel pump where that hose should go
There is hard line going from the pump to the filter and then from the filter to the carb. The vent line in the first picture is from the vapor cannister behind the right front headlight to the carb.
From the picture it looks like the needle portion is right where the fuel comes into the side of the carb from the fuel filter.
