I have a V1902 in a skidloader. I need new injection lines and all the associated o-rings and gaskets. Having trouble figuring out the part numbers and wondering if kubota made a special wrench to get the lines off the injection pump? Any help or advice appreciated. (I bought this machine on an online auction and they neglected to advertise that the previous owner bent/ruined the injection lines replacing the glow plugs and had an apparent fetish with blue silicone. (LOL).
