Pump to Carb Hard Lines

Looks good. Lets hope you don't have a fuel percolating problem.
Factory engineers moved that filter to a vertical position beside the timing cover in later models, About the same time they marked them unleaded fuel only.
I don't know that it makes a great difference.
I know the thicker base gasket under carb makes a difference. I did both changes to my 67 273. Cured it.
