last summer i made a pop tester with what i thought was one line of my spare injector lines, turns out i used one of my tdi ones!! will a brass compression fitting hold up to injection pressures for a while? i don't want to have to do this but $.50 sounds alot better than $108.00 for one stupid line!!! or better yet anyone know any cheap source for tdi hard lines? i don't understand why some sell idi lines for 10$ but no tdi ones?
