Is there a way to fix em when they get a hole in the line

These are in great shape but i just found 2 holes in one of my injection line.
Looks as though they met up with a battery or somethin arc'ed (sp)
Im not buying new one's at $196 a pair

These are on my set of BBC twisty's
I know im not the only one that has ran into this problem , how did you fix em? i think welding is a bit extreme they would probably melt
