No leaking fuel and I don't think there that old, I just replaced the one after the pre-filter the bubble in it is as small as I can get, all though some times there is a little one in the 90deg part.

If I remember correctly there where not any bubble in the clear fuel line post lift-pump after I stalled... All though they could have gotten pushed out when I tried to restart it at first... It has new style primer pump...
