Default Fuel line question

I'm doing an Ls1 swap in my 89 iroc, can I use my stock fuel lines or do I need to run a new one? If so where's the best place to get it? Thanks.

As long as the lines can handle the 58 PSI of fuel pressure, you're good.

I guess what I'm really looking for is something to connect my fuel line to the ls1 fuel rail.

No reason not to use stock type nylon lines. Inexpensive, light weight, small, and easy to work with. Lines and connectors made by Dorman are available pretty much everywhere. You can even order what you need from Summit Racing. Plugs right in to the stock LS1 fuel rail.

Assembly is pretty easy, and you don't need any special tools. I did it with a flare tool and a caulking gun.
