Old fuel lines just disintergrated over the years. I bought a packet of 3 different sizes from ebay 3 mtrs for about $9.
Fed a length of 15lb fishing line into the fuel tank, snelled a knot onto the tube and pulled it through. Two lines onto the tank, but an easy job.....
Just trying to sell it now, it rens well, plenty of power, just no bar or chain....
