What I did when I replaced mine last year was remove the moulded hoses take them to Napa and have them find similar hoses with the correct bends and diameter. If they don't have them in stock they can order the hose. Then cut the part of the hose that you need to fit your coach. They won't have your hose or a cross reference . It is easy to cut the hose to fit I even found a hose that I got 2 hoses out of it. The straight hoses will be easy as they sell them by the foot. It is a lot cheaper this way rather the order from the dealer.

Years ago I had to replace the radiator on my 2005 Diplomat. It was a good tie to replace the hoses. Rather than chase down the various ones I needed, this is what I did. I found an online company that sold silicone radiator hoses in 2". I took a pad of paper and measured the hoses I needed. For example.....if I needed a hose with a 90 degree bend with 12" on one side and 6" on the other, I wrote that down. I found I needed one another 90 that was 3" on one side of the 90 and 7" on the other. I also needed a 6" straight piece. I went to the website and ordered a hose with a 90 that 10" on both sides of the 90. I trimmed it to meet my 3"x 7" hose and the extra piece I used for the straight 6" hose. It sounds a little complicated, but was very easy since it was mainly straight pieces and a couple with 90's.
