Looks like 12677003 is different between the lt1 and lt4 as well. The fuel rails show the same part number for the lt1 and the lt4

I changed them out at least 6 times, I have a drawer full in my tool box. I would not hesitate to do that cause if you do have a leak on a one time use your screwed. Lt1 is 2200 psi and Lt4 is 2900. Don't be a fool and not change them.

Which fuel pipe comes with the magnuson 2300 kit when adding the supercharger?

Agree 100%. A fuel leak in that location and at that pressure...well, at least you’d be getting a new car. LMAO

Aj not pipes come with the kit so you can just buy those from GM. They are about 75.00 buck for the pair. My dealer kept them in stock, maybe I'm the reason why. Haha

Accordng to the magnuson 2300 instructions it comes with the attached picture is this not the case anymore. Or is it better to replace that line with the lt4 line that attaches in the same location.

How did you know they were leaking?

after seeing how the lines actually crimp on the ball end, i think you'd be a fool not to use new ones.
