Stainless Steel Fuel Lines
For the people that have converted to the stainless AN lines did you retain the stock hard lines under the car or run new aluminum line with AN fittings on each side....something like this kit from summit: http://store.summitracing.com/partde...5&autoview=sku
If you did retain the stock hard lines how did you attach the AN fittings? I was thinking on going with -6 with stock s4 TII rails.

I replaced my entire fuel system with braided stainless. There are no stock fuel lines left in the car, and the connections to the tank are made with AN bulkheads.
If you intend to keep the hardlines, there are many options.
You can flare the ends of the stock lines if they are in good shape. 37 degree flaring tools are avilable, and a nut slipped over the line will secure it to standard AN fittings.
You can braze or weld on an AN flare adapter. Make sure the lines are totally clear before doing something like this and disconnect at the tank end as well. Can be dangerous.
There are sleeves designed to allow connection of standard lines to AN fittings. They have a flared end to match the AN fitting and then a nut that screws overtop. I think Earls has them.
Be careful with the summit kit as it does not mention fuel injection. Some of the sleeves are rated for low pressures only.

I was thinking the same thing about the summit lines. I was going to give them a call to see whether they were for carbed vehicles with a low fuel pressure or if they could handle the higher fuel pressures of fuel injection. I was also debating about using the stock lines or not. They are in pretty good condition. I guess it all depends on whether those kits from summit can take the higher pressure.
