Hi Kent,
First of all, I HOPE you are getting along well and are much closer to normal....whatever normal is.....
Now, to answer your questions. I didn't really check the old supply hose where it connected to the fitting on the tank. After I got the old supply hose out of the coach, I cut off the end of the hose with the barbed fitting in it and we put the hose in the trash so it would go out that day. So I cannot say for sure for the supply hose. BUT I did see a few cracks in the old return hose where it slid over the barbed fitting to connect to the fitting on the tank. In fact, a couple of weeks ago, I put some tape around the return hose to cover those cracks and a couple of days later the tape was falling off.
So I would guess the old supply line wasn't in very good condition at the tank end either. The only differences I see in the portion of the hoses in fuel compartment vs. the rest of the hose is the hose outside (forward) of the fuel compartment and the raceway can be exposed to water and dirt from the road as well as possibly some more heat right at the generator engine. But the places where I did find cracks in the supply line were behind where the hose comes out of the generator compartment and were where it was bent to go through a clamp.
Since I did see some cracks in the surface of the old return hose where it slid over the barbed fitting to connect to the tank fitting, and considering the condition of the old supply hose in a few other locations, I don't think I would want to leave a section of either old hose in place. I think it would be just a matter of time before the old section would have to be replaced anyway and I look at it that I wouldn't be doing it any younger than I am now.....
Plus the supply hose on our coach went right into the bundle of hoses and cables that are routed over the tank. So access to the supply hose is still not very good there either.
If we could have removed the propane tank easily, I think it would have made the job much easier on our coach. But there was no way my wife and I could remove/reinstall the propane tank.
I used a hydraulic hose with a working pressure rating of 2610 psi, a nitrile tube and 1 high tensile steel wire braid at a cost of $1.47 per foot plus sales tax. I had to cut it with a hacksaw, but if you have a steel wheel cutting blade for a cutting tool of some sort, it should cut very easily. Inserting the flare fitting in the hose was quite a job...but it can be done to connect with the supply fitting on the tank. Since I knew what size flare fitting was required to connect to the return fitting on the tank, I had the supplier install a crimp-on fitting ($5.29 plus sales tax) on one end of the return hose so that simplified that portion of the job a lot.
I also purchased 2 each 3/8 ID 90 degree brass elbows with barbs on both ends so I did not have to bend either hose around the generator to connect to the bulkhead connector just upstream of the lift pump.
I am guessing materials cost around $90.00-$100.00 for the entire project.
I am very glad this project is done.
