Jim Twamely, first let me welcome you to iRV2.com. We are glad to have you join us here. How about introducing yourself in the New Members Check In forum. When you do you can just click on a new discussion instead of a poll. I am sure you will enjoy this website and forums.
You will probably not be able to get the old hose to pull the new hose through as it should be clamped along the way to keep it in place and not get chaffed. Since yours is leaking it sure would not hurt to try. You can certainly by pass the hose or even splice in at each end.
Good luck and keep us posted as to how it goes.

My own experience tells me that if I cannot specifically see a water leak, my chances of determining its exact source are not very good. Let's take a house roof, for example. Where water drips is usually not the place that it is coming in from the outside.

In your shoes:
1. I'd unfasten both ends of the hose.
2. Go to the plumbing store and get enough fittings to completely plug up one end and feed the other end with either air or water.
3. Fill the hose and see what happens. If there is a leak in the hose and you fill it will pressurized air, you should be able to hear it.
4. Consider what to do if the hose is pressurized but presents no symptoms of a leak

Many plumbing type leaks are construction errors. As Mike points out, there may be clamps along the route of your hose and, during construction, a fastener was driven through the hose at one of those clamp sites. Not only is that fastener causing the leak but it might prevent you from doing anything with the old hose.

This is all just guess work on my part but I sure have seen several similar situations and thought I would share my experience with you.

Jim, If the heater hose is as old as your coach(2000) it is time to replace the complete hose. They age at about the same rate as tires. I would replace the complete hose. Indiana Journey
