I have an RV based on the Ford E-350 chassis & V-10 engine.

Just got her running after sitting for at least 4? years. Hoping to put together a list of things I should do to get this thing safely back on the road. Starting with an oil change tomorrow.

Thanks in advance for your recommendations!

I'd try to siphon or drain the fuel tank. Run a can of Gumout "Tune-up" with your new fuel. It really works on cleaning! Probably a good idea to drain, flush and refill the coolant as well. The rest I'd play by ear.

 

I have a 94 Town Car that has been sitting for 3 years now. I was thinking to start it but worried about t he gas in the tank. I was thinking the best way was to drop the tank and clean it out. The ethanol will draw moisture/water that will settle to the bottom of the tank as well as the gas will separate.
Then again I have heard of people doing like Jeffrey said, just siphoning out the tank and were fine.
Then again we have a 77 Chevy truck that sets most of the year. Last year I was driving it somewhere and it quit running. I found nearly a qt of water in the tank and the carb was corroded inside the float bowl. But a 77 is not a sealed system..
Perhaps on the sealed systems the old ethanol fuel will not draw near as much moisture.

Gasoline Expiration - Ethanol Blend Fuels Have a Short Shelf Life

here is a sending unit out of my 85 that sat for many years before I bought it.

 

Annaleigh, I just read your link to the Ethanol site. I knew the 10% blend had no positive value (lowers thermal energy in gas and takes corn out of the food market for a lower priority) as it ate a couple of lawn mower carbs and I switched to 100% gas for those after learning the cause. In my small town it's only available in premium. That 50-60 cent price spread is hard on the budget for a vehicle that gets 13-14mpg mixed. Wish there was a way to buy Sunoco 260 again.

 

I don't want to hijack the thread so I will post this and drop it!!!
I would like to follow the money trail that led us to ethanol.....
Increasing energy use, climate change, and carbon dioxide (CO2) emissions from fossil fuels make switching to low-carbon fuels a high priority. Biofuels are a potential low-carbon energy source, but whether biofuels offer carbon savings depends on how they are produced. Converting rainforests, peatlands, savannas, or grasslands to produce food crop–based biofuels in Brazil, Southeast Asia, and the United States creates a “biofuel carbon debt” by releasing 17 to 420 times more CO2 than the annual greenhouse gas (GHG) reductions that these biofuels would provide by displacing fossil fuels. In contrast, biofuels made from waste biomass or from biomass grown on degraded and abandoned agricultural lands planted with perennials incur little or no carbon debt and can offer immediate and sustained GHG advantages.

And not to mention all the repair/replacement parts that have to be manufactured for automobiles and other machines due to ethanol problems. Nor the fact that as the machines start having problems, they burn the fuel even less efficiently. And the farm equipment that has to be replaced, often by poor farmers that can't afford it.. SO I am not sure Ethanol is going to save the planet!
