They usually crack about a 1/2" above where it enters the tank.

thank you for the replys . think you could give me a brief discription of how to get to that part of the line please? ive never really taken the saw appart at all.. the airfilters about all the farther i have gone into the saw..

It's hard to see without taking the fuel tank off. But you can peek in there by removing the side cover & taking the bolt out that holds the handle bar clamp that hooks to the cylinder mount.

See pictures below

thank you very much i have a feeling you might be right about the fuel line.. would it be making a sucking noise if there were a cracked line ? becuase it seems it is making a sucking noise that may be comming from right where you are talking about .. is that little black nob down there bye the fuel line the tank vent ? or is that something else?

The fuel tank vent is on the recoil side of the saw. You might be seeing the rubber flaps under the air box.

however the saw does have some problems that it should not, in my opinion.

That is my fealing as well.
Despite what the Dolmar dealers on here say,THE BUBBLE SAWS HAVE ISSUES.
