Stock fuel lines handel pressure of LS pump?

So I'm getting ready to swap an LS3 and TR6060 into my 1991 C1500 to replace the 4.3L in there now. Since I've got feed and return on the truck already and the LS3 has 2 lines I was thinking of using stock fuel lines to feed the new motor but curious if the lines made to supply TBI pressure can handle the 58 PSI required of the new engine. I'm definitely not leaving the 25 yr old lines so I'm replacing anyway and trying to figure if just getting replacement lines rather than stainless braided hose would work. Anyone running stock lines with no problems?

Yes your stock fuel lines will be fine.

Yes stock lines are fine did on my swap. I just bought the adaptors to make connections to fuel rail

I would use stock fuel lines on 96-up truck. The TBI trucks had weak rubber sections that were designed to handle 15 psi from the tbi pump. No way in hell I was about to use my stock fuel lines on my 95. I went with all new stainless braided and an fittings
