Pressurized Water Filler Tube

[LHall]

I am considering replacing the black rubber filler tube that runs from the valve on the outside of the trailer to the tank under the kitchen sink. I have a 62 Ambassador with a pressurized galvanized tank. It appears that the current hose is black rubber similar to an automotive radiator hose. The system has no leaks and holds pressure, however I noticed a small hairline crack in the outer skin of the hose and want to replace it. I have not been very sucessful in my search of this topic on the forums. I believe that the inner diameter of the hose needs to be 2-3/4" Has anyone done this replacement and what material was used? Any advice is always appreciated.

Thanks,

I would use tygon tubing

The original filler neck was fastened directly into the metal tank with a section of pipe.

No hose was used.

Too funny! US Plastics is one of our suppliers for the Tygon we use on our presses! They are really great to work with and their Tech Support is pretty good too! You will find they have lots of cool stuff when repairing or upgrading your AS. I even buy stuff just to make more stuff around the house!

Thanks Andy,

I will have to remove the hose and see if there are threads under there and try to replace the pipe section. The rubber hose is pretty old and looks like it could be original.

You can pressurize your water tank to 100 psi.

A rubber hose would never take it.

Just what kind of rubber hose are you talking about? We have rubber hoses in airplanes that will take 1000-1500 PSI, reinforced of course.
