Fuel lines on my 91 Z28 are shot. Lots of rust. Can I buy 3/8 tubing and use tubing to AN fittings to replace it all? Instead of using the stock saginaw fittings with those crappy orings, I thought it would be easier to run the fittings at the fuel sending unit and to the front of the car to 6an. Also if I do this does anyone know what size the fittings are on the inline fuel filter?
