Fuel lines -- Steel to plastic ???
Which fuel rail? You need the one that works with the injectors for the intake you are using. Most of us are using the single feed style, but there are some setups that need a return line from the fuel rail. A decription or pic of what you have please...
99 Vette. Than a call to Swagelock for a 3/8 to -6AN and a 5/16 to -6AN. You will also need the quick connect fitting to a -6AN. We used another 3/8 swaglock and the tube from S&P, however there is a thread on here somewhere with a Dormann part number for the tube.
Take a few minutes and learn about the -xAN fittings, and braided line assembly here:

We did not use any flair fittings, only -xAN or Swagelock compresion fittings. Please take a look at the fluid drawing for our system and the parts spreadsheet which you can find here:

This is not the only way to get there from here, but it is what we did, and it works. Do not buy the braided line from the fuel rail down to the frame rail, make that guy yourself. Like Shifty' says, "Braided Line is Stupid Easy to Make!"

I`m cheap and reused the stock plastic flex lines off a v6 4th gen camaro
. I didn`t even buy the dorman ends, I just cut the steel fuel line of at the yard, then I double flared it and used a union to connect it to regular steel fuel line. That way I had the quick connect ends and plastic fuel lines. I did the same thing on my 4.3L chevette, the GM plastic fuel lines are so easy to work with/quick to connect and to top it off they are dirt cheap at the boneyard. You can also use a compression fitting to join the lines if you don`t have to tools to double flare them.

LS1 Fuel Hose or Fitting Sizes... -6 AN is 3/8" line or fitting size. -5 AN is 5/16" line or fitting size. On an LS1 engine, the 3/8 fuel line is the fuel supply line to the engine. The 5/16" line is the return line size. The '99 Vette filter/regulator has two ports coming off the rear. One is supply from the tank(3/8"), the other is 5/16", a return to the tank. The one port on the front end of the filter is 3/8" supply, going forward to your engines fuel rail. The filters are labeled for flow direction.

There are lots of different ways to go, buit since I wanted my install to look "factory" I used a flaring tool made by Mastercool to make the push connect flares on the steel fuel lines and a kit made by Dorman to make the plastic GM type fuel hoses. I also swapped the fuel rail 180 degrees so the inlet was on the passenger side the same as the factory steel fuel line.

The Dorman PN is 800-300.
