I run standard aluminum fuel line, Steele braided lines between the tank and pump, between the regulator and carb. I use summit inline filters and a Holly 12-125 pump. I use a Holly regulator. Four years and 800 passes on this setup with no problems. The only maintenance I do is before I put the car away for the winter. I drain the tank and float bowels, put one gallon of 100% gas in the tank, turn on the pump to purge the lines, start the car, let it run for a few minuets to burn away any E-85 that was in the lines, turn off the pump and let the bowels go dry. I then shoot WD-40 into the bleeds.
