Anyone know qhwew the 3rb runs to in this device. Its the small vacuum pump that fits after the fuel filter. I have the intake correct and out pipe but dont know the smaller pipe. There is nothing there at the moment due to me just putting all back together. how long id the tube? I do no recall ever taking it off when I stripped it down. http://www.ukmonster.co.uk/monster/s...t=58838&page=8
