i am fed up by constantly breaking vacuum hoses for my carb. i am always feeling intermittent rough idles w/ or w/o a/c almost every other month only to find out that i have a couple or more cracked vacuum hoses. i had those cheap ones bought at auto supplies and mall hardwares.

i was just wondering, where can i buy good quality vacuum hoses? i've asked mitsu casa and they just referred me to outside auto supplies. the shops such as atco, eldo, mitsuprime, etc. only have the cheap ones. the cheap ones are characterized by the soft body that when flexed "immediately" cracks, unlike the original hoses that takes years before they eventualy crack.

where can i find a good quality vacuum hose?
