there are 2,1 is smaller than the other.what i did is because thay were 2 driffrent sizes,i got a (t) connector that lets you use driffrent size lines,sniped off the end of the t connector to match what size line i had and ran just 1 new line up under the center pod on the handlbars.its real easy to do if you have the right parts. ps make sure you get a vent hose long enough,someone on here said to get 3 feet. was not long enough for me i went back got 5 feet just to make sure.
