I want to change the stock fuel line to the fuel rail and run them out the rear of the engine instead of up front where they are now. I also want to use 'normal' fittings. This is on a 2002 LS1.

Any tips on how to modify the fuel rail to accept 'normal' type fittings?

Is this just for asthetics?

Yes, asthetics. The 61 is painted LeMans blue and I want the strip to pop. It's currently Dover white, the only white offered in 69, but it looks more yellow than the strips on the hood of Camaros
