Bubbling orange leveler hoses

[Watertown]

Got the rv out and getting it ready for a long trip next week and found the dreaded bubbling orange hose.
I know it's an old thread somewhere, but I can't remember the exact fix. Not a real problem to do it myself just need the part numbers people used and the hydraulic bleeding steps.

If you replace them with the same thing the problem will likely repeat it's self.

Pull them off and go to a Parts House or tractor/farm supply and get new hoses made IMO you will be money ahead.
