Fuel lines

Hey everyone.

Swapping to LS from carbed car. Years back I had already swapped my barbed hose ends for the AN compression fittings and they never leaked. These are the ones with the copper compression fitting in them that tightens down over the tube.

Will these work with the higher pressure the LS requires for FI or do I need to swap them out?

Fuel pump is wahlboro 255. Installed it about 10 years ago when I went to the compression fittings during my last engine swap. I swapped my 305 for a 355 and got rid of my mechanical fuel pump. now the 355 is going for the LS.

Link here and picture below.
