Fuel Line Mod???
Fuel Line Mod??? Does anyone know of a mod on the LT1's that re-routes so to speak the fuel lines? i hate how they come out of the strut tower and then wrap all the way around just to go strait to the BACK of the damn intake. 
Here is mine, I just came up with something on my own. I have a write-up about it that I can post for you.
To complete the fuel line and the EVAP line delete modification, I used Pure Choice Motorsports (www.performanceplumbing.com) fuel line AN fitting adapters (part #5800) to adapt the -6AN fittings to the fuel rail feed and return line and also to adapt the -6AN fittings and braided lines to the hard lines under the car. The Pure Choice fittings slid right on the fuel rail but for the hard lines under the car, I had to use some very fine sandpaper and then some fine steel wool to get them to slide on. I don’t really know why this is, because they are the same style line fittings. I don’t know if it as just because of all of the buildup from the road grime, salt, sand and etc., but that it what was done to get them on. After removing the driver’s side inner fender, you expose the stock fuel lines and you can easily remove them and the EVAP line. The EVAP line runs with the stock fuel lines from a hard connection beside them under the car on the driver’s side to the intake manifold where it separates and attaches to a module and vacuum line. I simply removed the EVAP module and the lines completely, used plugs to plug the extra openings in the intake and used a rubber cap to cap off the hard line under the car next to the fuel lines. You will throw a code on this but I was going to have a tune done anyway so I just had it tuned out. This really cleans up the engine bay once you delete the fuel lines also. Next, I found a good spot to run the new braided feed and return lines in the inner fender, where the would exit just below the master cylinder. I drilled two holes next to each other just large enough to get the lines through and then used rubber grommets to protect the fuel lines. I attached the lines to the fuel rail after routing them over the top of the master cylinder and then routed them under the car using the location of the stock fuel lines. I then cut the lines to length and attached the last AN fittings and attached them to the hard lines under the car. I have pretty good pictures of all of the lines mounted under the car at this link if you would like to reference them http://img212.exs.cx/gal.php?g=benscar9mx.jpg.

It actually wasn't that bad, I can't really judge how long it took since it was a winter project and I took my time at it, but it is fairly straight forward and as far as the EVAP, I just removed all of the lines and equipment and plugged the excess openings.

I have to chime in on your car as I looked over the pictures. It's fabulous and for all practical purposes, It's immaculate; something I can only dream about. What kind of time do you think you have put into it? How much do you have invested? Cars are art and yours is a masterpiece! Congratulations and thanks for sharing the pictures....
