Ethanol is not kind to older automotive systems. In my GMC motorhome, it has clogged the carburetor to the point where the engine would not start. Solution: the shop shot the carb with "Gumout" until the goo disappeared.
It has clogged two of three fuel filters. It may have destroyed the Onan fuel line fuel pump-to-carb, which cracked.
It loosens deposits in the fuel tank and is not compatable with original type rubber fuel lines.
A solution is to drop the fuel tanks, have them cleaned and replace all rubber fuel lines and vent hoses. You will need the following:
3 feet of 1/2 inch fuel line
24 feet of 3/8 inch fuel line
25 feet of 5/16 inch fuel line
10 feet of 1/4 inch fuel line SAE Spec R7
Part of this goes to the fuel cannister up front and some also goes to the Onan or Honda generator.
Use Stainless Steel clamps.
It is suggested to cut the fuel line before the fuel separator, connect a small electric fuel pump and pump the tanks dry before lowering. Fuel tanks weigh about 45 pounds each empty.
The information on replacing the fuel tanks is from an article on the net entitled "Fuel Tank and Exhaust"

I would add to check and perhaps replace the fuel sending units and/or the socks attached to the fuel sending units.
I will attempt to describe our experience doing this procedure as I am tired of ethanol problems, sputterig engines and clogged fuel filters. After this, the "Yellow Rose" will be for sale as we attempt to upgrade the Edgemonte to roadworthy standards and beyond...........Michael at GEMRECS
