Looking to make some fuel rails for an upcoming IC project. I wasnt to just cut up some stock l67 rails and ad some stainless steel lines. Pretty much like these from ZZP
ZZPerformance - Modified Fuel Rails #09-01-00534

Much rather do it myself and save some pennies. So What kind of fittings and line would I need to do this, like sizes and such? I read bills thread about stainless fuel lines but that seemed a little different than what im trying to do lol
