hey i figured it would be a great help if we could try to get the size fittings we need to rerun all of our lines in ss line. might be a dumb idea but i know alot of people want to know what size fittings they need. i need to know what size fittings i need for hayame fuel rail input and fuel filter. ill guess and say prolly 3/8" npt on the rail and 1/4" npt on the filter. any1 know if this is right?

 

If your fuel needs arent actually in need of being bigger and you just want it to look cool then use 1/4 npt by -6an for the feed side. the ID of -6 is 5/16 hose.
