Replace all the fuel line and try again. I've seen brand new fuel line have tiny pin holes that allow air in but won't let fuel leak out. A issue like this, I would replace all line and try again.

If you have the fuel line really close the the engine head like how they come from factory this will heat up the fuel and create air bubbles . If this is the issue route some new fuel line so it stays clear of the engine head .

might be bubbles caused by the fuel sloshing around. If it still happens after you've replaced and rerouted the lines, ignore it.
