Will the fuel line assembly from a 3.8 work for an ls1? Theres one on ebay A while back we where trying to pry my bmr torque arm away from the trans tunnel and somehow we got the pry bar stuck on my fuel feed line and we made a big ol crimp in it. Is it affecting my fueling I'd like to assume so because it's a big old bottle neck up by the trans tunnel. And since gm doesnt carry it anymore I cant fix it, I did have the idea to cut it and spice in a new peice of line is that possible has anyone done it before?

Seems like compression fittings or flaring the line and replacing the segment WILL work. Flaring would be best.
Ive done it 30 or so times with gm brake lines near that area.

taking the gas cap off and purging the fuel rail will do this but you will still loose quite a bit of fuel, all that is in the line. Should be about a 30 minute job if you have tools on hand

Removing the cap will not relieve any pressure. Pressure is held by the fuel pump. You can relieve a lot of it by pulling the fuel pump fuse while the engine is running.
Then place a rag under the schrader valve on the fuel rail and push the valve core to finish the job.

My guess is that they are not the same since the older 3.8 uses a return type system, and LS1 is returnless.
On the other hand, the shape of the lines will certainly fit the underbody contours, so even if it's different, you should be able to make it work.
But you are going about this the hard way. Just patch in a repair line. Fuel pressure is only 55 psi, so compression fittings will do the trick. Should cost about $12.

Fuel Lines I doubt that the fuel lines off of a 3.8 would fit on your car. I have some fuel lines that came off of my 1998 Pontiac Trans Am WS6. If you're interested in purchasing them just let me know.
