    In doing the valve cover gasket job I’ve noticed quite a few of my vacuum lines are cracking on the ends.
    What is the best option? is there a kit or do I just bring the lines to the parts place and get the appropriate size lines.
    Thanks

    Just figure out how many feet / meters you need, check the inside diameter of the vacuum line and go to an auto parts place and buy the amount needed in which ever diameter needed. Then replace it one piece at a time with the same routing as the old piece. You could nip off a piece of the old for a sample to show the parts house if needed. Buy the best quality vacuum tubing they sell, it will last longer.

    Spray them with AT-205 and they won't become brittle & crack. The spray can restore brittle rubber that hasn't cracked yet.

    On some of my hoses, I’ve cut just the cracking portion of the tips off and re-connected with no problems. Most of the hoses have a little extra length to make this happen.

    Key Notes: Be clean and precise with your cuts. New Factory Hoses are High Dolla!!!

    I have done the same, but I sprayed them with re-seal as I was putting the fresh cut ends where they belonged. It's good stuff.

    This reseal seems like a good idea. The Hoses mentioned above that I cut were done about 5 years ago and they still look new on the tips. I do have one Hose going into the Air Intake Box that is currently suspect and have considered smoothing some Toy FIPG 103 on it as there isn’t much slack to cut the tip off.

    Also, all the Hoses received some Ziptie love to keep them all organized/bound up in their OEM Clamps.

    If a hose is cracked, its just best to replace it. You will save yourself a lot of headaches in the long run. vacuum line isn't that expensive.

    While I agree with your basic premise, many of our hoses have custom bends and turns specific to OEM Fitment.

    Replacing with inexpensive standard straight hose may work in some but not all applications causing other problems in Vacuum thus the OEM Price dilemma. Cutting the tips works as the rest of the hose is perfectly fine. Haven’t tried the sealer trick yet but we’ll see on that one.
