Has anybody used the Granatelli tank insert part # GM-t17998 with the stock bird tank? Fit the opening ok? Any other suggestions would be appreciated.
Not sure. You could order it and trial fit it to see if its going to work. i would think if you were careful you could return it if necessary. I just sumped my tank with a Competition Engineering sump and went on.
