Running new a/c hose for dash air

Zeb brings up a good point if you drop the water tank it will make running the lines easier although I managed to get the new hose through there with out dropping it but I was only doing the high pressure hydraulic hose for the power steering. .in the wet bay I created an opening in the wall between the wet bay and the basement big enough to be able to reach in over the tanks which helped but it's still a very tight area to work and even with that opening you cant reach all the way to the rear bulk head .
Speaking of the high pressure power steering hose you may want to inspect yours on my coach it ran up the inside of the right hand ( passenger side) frame rail and then turned sharply behind the gen set over to the driver's side through the other frame rail and onto the power steering box.
Where it made that sharp turn coming out of the passenger side frame rail it rubbed or chafed a hose in it on the frame cross member causing a power steering leak and failure fortunately it happened in my yard and not 3000 miles from home.
If your going to all the effort of dropping the water tank it would be a very good time to think about changing the heater hoses which run from the front back to the engine and tee off to the Aqua hot as well or at least do what I did as my hoses looked pretty good where I could see them I decided to install a pair of ball valves inline in the heater hoses in the engine bay so that if I ever did have a problem with one of those hoses or heater core leaking on the road I could isolated them to get me home or at least to some where I could replace the bad hose or heater core.

Hope this helps
Eric

Zeb Severson:
Thats a good point Eric about checking the other hoses and adding ball valves. My slide hydraulic were blistering, and were routed poorly through the frame rail where they were cutting into the hose. I will make sure I will check on what hoses I can see and get to my new chassis lube.
