Nice name for a cat, but no.
Having rebuilt my downed nextar using all original internals, I now seem be plagued with bubbles in my fuel line. Tank on Nextar has 3 lines if it makes any dif, extra line is a fill line.
So what causes air in fuel?
I have a nexstar.. There isnt much you can do about padding around the fuel tank because it already has a "mount" inside of the plane.
Have you tried a different prop? On a plane I had, I had an APC 11X6 on it and it vibrated so bad it was causing bubbles.. Put a Master Airscrew 11x6 on it, no problems.. Make sure your prop is balanced.. If not, try a different prop and see if that helps.
