    from the petcock..one fuel and one vacuum.. fuel is the larger diameter..vac the smaller..your outlets off the petcock point towards the rear of the bike and the 73a model towards the front..vacuum pipe length and internal volume WILL affect fuel flow rates and a/f mixture levels..it should in theory only open and close the petcock but it does weird stuff from 10-11K to the red line..strangely enough only on cylinder #2!! stick to the standard hose as i havent been able to better it to get through the 8-10k flat spot all the 4cyl 4 stroke 250 suzuki's have..pictures mate..pictures!!!! Here to help if i can matey,
    Cheers, si
