Rotten generator gas hose

The fuel hose to the generator is leaking near the gas filter connect. I tried trimming it and the end is rotten. The Rv is sitting in storage, covered with a full gas tank.. It is also cold and windy here now. I cut the hose up by the frame and put a bolt in the line and clamped it.. I pulled out the bad hose and it seams to only be rotten and swollen in the last 8 inches.. For time and money I am thinking about splicing on new hose to the generator. First few feet would be old, last 2 ft new.. Any ideas. The hose is SAE 30R7..not sure what that means. Needing suggestions
Thanks, Don

SAE 30R7 (DIN 73379-2B) = Low Pressure Fuel Hose per google.

+1 on full replacement. Ethanol in gasoline has been shown to shorten the life of fuel lines. They used to be good for over 10 years, now 5-7 is about it. If you buy new hose, it may be improved in this respect.

I would patch it till I could run the gas out of the tank-then replace the hose.

Look under the rear bed for a cover to access the tank. I don't know anything about your motorhome, but when I had an issue many years ago with my '87 Bounder, there was a cover.

Hose is cheap so to speak, get 10 feet( or what you think you need plus a couple feet ) replace what you can and properly anchor it, maybe leave a little extra at the generator end, splice as close to the tank as you can then coil and secure the rest.

Then drive down the tank to where the remaining can be drained into as many borrowed gas cans as you can find on a summer day and finish it then.

Ours is 150 gallon, heavy steel and huge, so the coil is right in front of the tank, likely will be like that for years...

My generator supply hose developed a hole and didn't leak but sucked air. I had to pay to remove the fuel tank and 1 hydraulic jack just to replace a $10 hose but its one of those things you have to just fix and not worry what the hose cost.
