Hahaha, nah Ali's a great mechanic, i think its just something wrong with my car, ever since i got it the hose keeps cracking and coming off. But this is the first time from the unit side. I've put it back in to a barb, not sure if its the right one, coz my boost gauge is not working and stuck on 0. So either its in the right barb and my boost gauge is now broken or its in the wrong barb. But its boosting properly now, so i think its the gauge. *sigh*
