thomasgibbens Posted October 30, 2022 Share Posted October 30, 2022 A moth or so ago I posted that I had a broken hydraulic hose right at the pump. Cummins turned me down as they said they couldn’t figure out the routing but they just didn’t want to take on a dirty job! I took my coach back to the REV service center in Decatur and they put on a new hose and filled it with Dexron IV fluid and said it was good. We left to go home and got to the campground and the new hose blew out of the fitting and emptied the reservoir! We are now back in Decatur for repairs. My question is why would that hose fail? Can the pump over pressurize the system? We had not even tried to level the coach. I stopped at a rest area about an hour before and there were no leaks then. Does the pressure in the pump vary or is it constant? This system only serves the levelers and not the radiator fan or power steering I’d like to hear your comments so I have a better knowledge of this system.
