Has any one every had to replace this tube. I just had a replacement motor installed and my warranty company said it was not covered even though it was on the motor they sent the dealership. The dealership want $225 to install this. I was wondering how hard this is to do on my own? Any advice from any one would be very helpful. I would love to be able to check my oil as I cannot not since there is a big kink in the top of the tube.
