fuel line question

well i was looking around the engine bay in the 94 and i noticed the two rubber fuel lines that come up under the tb and i was curious if they make a braided replacement....one feels really loose and both are looking pretty weathered....i went to russells page to look there and found nothing which surprised me becasue 2 years ago i bought the same thing for my 93 .... need help if anyone knows anything

crap....im trying to get this thing prepped for the bottle and that qick disconnect is scaring me one line has no play at all and the other i can move a lot i didn't pull hard enough to see if it would slip off or anything but i got movement and a good amount i want a solution for it....is it factory rubber hoses or is this some other owner did?? if they are metal tubing factory i will get them.. i just dont like the rubber high pressure fuel lines i really want a braided solution if anyone is running them on there cars please let me know where you got them
