Last week we had the fuel lines replaced by MOT. Keith Risch supervised the job and actually did a lot of the work. But he was assisted by Clyde and Dakota, two of the other service techs at MOT. We were there for most of two days. The fuel line replacement might be able to be completed in a day if all the replacement hoses were available but they had to be ordered with a next day delivery.
The process of replacing the lines is what you would expect. The fuel tank was slid most of the way out on the driver's side (I had removed the covers earlier). The bay door and most of the hardware around the bay opening had to be removed to get the tank out. When I brought it in I had about 1/4 tank of fuel, but Keith has a very large container (~200 gallons) to hold the fuel if he polishes it in the process of emptying the tank. He circulated the fuel through his polishing set up and back into my tank for about an hour to help remove any residue in the tank. I used my "endoscopic" camera to check out the tank after that treatment was complete and it looked pretty good. There were some particles on the floor of the tank which appeared to be pieces of aluminum from drilling out the openings in the tank for the inlet and outlet fittings.
After the fuel was removed and the tank pulled out, the laborious job of pulling the new lines was undertaken. Three sizes of black rubber hose were used (5/8", 1/2" and 3/8"). The latter was used for the generator which I also had done. The cost of the hose alone was about $800. I looked over the old hose and did find some cracking, but the big difference between old and new is in the flexibility of the hose. The old stuff was very hard and stuff in comparison to the new. The hose definitely needed to be replaced. The new hose was pulled through by connecting it to the old and then pulling it through. Not an easy job. After the new hoses were in place, the tank was pushed back into place and rebolted. Then the fuel was pumped back in after running through Keith's polishing setup. The fuel that was taken out had a slightly cloudy greenish color even though it had been filtered, while the polished end product had a nice clear yellow color. Next, the bay door was replaced and the rest of the hardware that had been removed. Finally, the engine and generator were started after purging the air in the fuel system. It was a big job and one I'm glad I didn't tackle on my own!
I continue to be impressed with Keith and the other techs at MOT. They all seem to be very hardworking and skilled. Another thing I really like about MOT is that their shop is not a "black box" so to speak. The customer is free to hang around and see what is being done. Questions seem to be welcome. Attached are some random pics of the process.
George how much for the job? Mine are original. Something I'll have to have done in the future.

Mike... about $800 for hoses and $2100 for labor. This was for the engine and generator. We do not have Aqua-Hot.
George
George,
Do you know what brand and style hose are they using now?
Mike
Mike.... I kept samples of all three hoses. Each sample has the imprint on it, but they are packed away. Black (NOT red) reinforced hose. Made in Mexico.
George
Mike it would be interesting to see what hoses are used. The hose I got from FT is light brown, slick and smaller than the original. I am going to finish my job this winter.

Anyone that wants to do it themselves,I bought all my Parker hose at House of hose in Spokane Wa.. What they use for everything, including commercial use.
Right at $200.00 with all new brass fitting installed by them.
Been installed 2 years now, no issues.
Took me an easy 2 days by myself, just milking the job.

My post when I did it:
Fuel Line replacement (https://www.foreforums.com/index.php?topic=31903.msg283216#msg283216)
Just had my hoses for the engine and generator on our U270 changed last Thursday at MOT, They had deteriorated and the generator hose has been spliced. There were three techs working on it, they started at about 2 in the afternoon and finished at 5 o'clock with a half hour putting back panels on Friday morning. As to the price, have not got the bill yet!
Did it myself. Wasn't a difficult job. Just time consuming.
George,
I had my fuel lines done last summer at MOT. Engine generator and Aquahot. I arrived with the fuel low level warning light on. I had never run it that low before and plan never again. Anyway, they did not have to remove fuel which I think they appreciated. On my coach they pulled the tank out the passenger side and only had to slide it about a quarter of the way out.
It was a day and a half job but they had it together enough that we could back it out of the bay and stay aboard at night.
Very happy with their work and appreciated that I could hang around and watch the process. (I love manual labor, I could watch it all day).
