im putting an ls1 into a 1990 240sx lines look like crap on the hanger so i was thinking about redoing the fuel lines since they look like crap is it worth it to do braided stainless lines the entire way or should i just leave them metal and swap to the an stuff up in the bay? also for fuel pump looking for a recomendation is a walbro255 good enough? i am thinking about doing e85 this winter and fuel line size should i stick with my cars stock 5/16 size or go to 3/8 ( 6an)

Run solid line as much as possible.
Up grade to 3/8 line if you are thinking of running E85.
I would recommend purchasing preformed lines.

Ok I like the idea of hardline better I was just gunna get 3/8 brake line from my work to run most of the way I just didn't like how off the tank its just hose clamped rubber line

3/8 brake line, now you have let the cat out of the bag, that is what I use too.
Now every one is going to use it.
Modern fuel is corrosive to rubber hose. Replace the "Rubber" hose with Teflon, (PTEF) hose. There are compression fittings available to adapt AN fittings.
