Well sure, any air leakage will make it tend to lack fuel supply.  What kind of fuel tanks do you have?  Is the air sound you hear at the coupling to a regular 6-gallon tank?  They often leak at the little pins that the hose coupling push in when connected.  The original ’58 tanks were especially bad about this.  But the newer ones also will do it.  They are repairable.
