mccollough saw parts

[win38mag]

I've been cleaning out dark spaces and have brought into the lite some saws from 20 plus years ago. a mini mac 120,320 ,330,and a promo 610.  plus some parts.  I decided to see if I could get them running and discovered that the parts I have aren't the one's I need !   Oldzimer's thing I guess. 
    Heres what I'd like to find......For the 610 
      1) a gas line ..tank to carb,that has the sealing nub for the tank.  Or some ideas as to what other's have done to stop the gas from leaking .  Does anyone know if there was a gas line clamp on the line at the carb or was it a slip-fit connection ?
