Motorcycle Repair: zxr250, vent hose, fuel petcock

Question
how do you conect the hoses from the carbs to the vacuum. there is 3 thick pipes and one thin one. please can u help

Answer
Im not sure how to answer this but the vac hose on the fuel petcock is usually the smaller hose and goes on the port tube closest to the intake on the head the fuel lines one a main and the other a reserve line go onto the carbs. The extra hose may be a vent hose for the tank.
