they sell it by the foot, less then a dollar a foot too. if you get about 4 or 5 feet, thats more then enough to replace the vac lines.
you may need a fatter hose, then push a thinner line inside it and a T or a Y for any evap lines.
it cuts with a razor like butter.
some pics of my lines.
evap off the TB, the fat hose there looping to the back of the engine has a hose inside the fat hose, then to the plastic line. this goes to my evap solenoid.
this line runs from the boost by pass to the fuel pressure regulator with a T, then under the snout to another T, then it ends at the map sensor.
