I had this same hose blow out on me on the track during my 1st DE event this year.

It was not that bad changing it out, you just need skinny arms and some determination. The spring clips being different sizes did catch me during the reinstall and it took me a while to figure out why one would just not quite fit right.

I changed all the coolant hoses after that little mishap on the track, figured they are all getting on 9 years old. Btw the other hoses did not look that bad off compared to the one that had a 3" long split it in it.
