Leaf Blowers

I have many husqvarna products. I have a blower 145bt that is leaking from the gas cap. It seems to be an issue...I know that if husqvarna were to admit it, they would have to recall or replace all of the gas tanks etc. How can I fix this? It's not fair if several people have the same problem...please send me what I need so I can fix my unit as it's a safety concern.

Thanks,
