I would like to run braided ss lines but for forty bucks ( been spending too much money already on the car[&:]) that I'll go with copper lines..... but would the copper line be flexible enough to do the loop thing from the article?

Thanks,

Oh, does anyone know if they make 52mm gauges that measure how much fuel you are using.... like the ones that come in luxury cars that tell you how many miles per gallon your are getting? (because i need one more gauge to fill in the third hole in my 3 gauge pillar)
