Otto I have seen fuel line turn into a brick over night. Put some in a chain saw. After replacing the fuel lines. Ran it ok. Came back the next morning to finish up. Fuel lines were rock hard.

Plus when it first came out. I was involved with a boat that blew up and killed two people. Found out after I left the boat. They had gone to the fuel dock to fill up for the weekend.Filled up with the first load of ethanol the marina had come in. After going through what was left of the boat. Found the fuel lines had turned to mush.

Got any numbers? The ethanol plants are all making money here with the current price of corn, natural gas, and gasoline. They also haven't received any subsidy for a year now. Their margins are lower than they used to be, however. If gas drops down to $2.50 without a corn price drop, they would probably lose money.

Your supplier needs to sell you fuel line, not vinyl tubing suitable for aquarium aeration.

I've seen rubber fuel lines on new air cooled engines turn as stiff as a piece of wood and rubber diaphragms in carburetors as stiff as cardboard due to the use of ethanol fuel. These were not problems before ethanol, or at least in not as short a time.

The fuel line was rated for gasoline fuel systems.

Lot of "plastic" parts in old engines are not rated for ethanol.

It you go to an o-ring manufactures web site and look at chemical compatability tables you see many "plastics" are compatable with gasoline , but not ethanol.

When ethanol gas first came out some 20-30 years ago, cumberland farms sold alot if it, and eventually paid alot of lawsuit. It ate the rubber/pastic parts of carbs, because of chemical in-compatability.

Just replaced my intank gas pump in 92 Chev that sat for ~3-4 years. Motor laminations were rusted to stator, copper comutator was surface corroded to so high restistance, that NO current flowed even with 24 VDC applied (measured it with my meter).

To safly run ethanol , the "rubber/plastics/metals" exposed to fuel have to be rated for ethanol compatability. Which basically means you need a newer car, made/designed for ethanol. I guess even the aluminum castings get a metal coating to make them compatable with ethanol.

And I guess if you have an older car, you can't let it just sit (like I did). Guess ethanol sucks up water from the air, and that builds up and causes corrosion of unprotected metals.

They are likely metal, they likely will only get a light surface corrosion. I think it's the tiny passagways in things like carbs that get plugged up by surface corrosion. Maybe his carb's internal aluminum parts have a manufacturer's coating/plating to prevent corrosion. If plastic lines, car part store could have switched to ethanol type gas lines so they wouldn't have to stock 2 types.

Factory metal fuel lines run through interior of HER car, rubber lines connect to in-tank fuel pump, and from firewall to the injector pump, injectors are stock yet modified to deliver more fuel

If the car has injectors it's very likely it was made after the problems with ethanol surfaced ~20-30 years ago, so the rubber/plastic/metal parts of her car are likely ethanol compatable, from the manufacturer.

Other possiablities come when someone/mechanic has an OLD roll of gas hose (not ethanol compatable) that they want to use/get rid of.

Looks like a good place to post a link to my video again....

http://youtu.be/SDqefZuMenU

1937 Ford truck Flathead V8 after setting for 14 years with a broken spring in the distributor. Rebuilt the distributor, put in a new battery, and fired right up, running just fine on a mixture of 15-17 year old E10. Other than priming the carb with fresh gas to cut down on cranking time, NOTHING was done to the carburator which has still not been touched since I rebuilt it in 1978 ! No carb cleaner, No idle adjustments, No Nothing.

It's a very short video of it running in the shed, but after I shot it, I pulled the truck out in the yard where it ran for a 1/2 hour or so before driving it 4 miles to the nearest gas station to add a few more gallons to it.

That was with a 1/4 tank (or less) of E10 setting in a building with a dirt floor and high humidity for 14 years with a vented gas tank.

No Problems what so ever. I've had to replace the points and battery a few times over the years, but I haven't touched the carb in 34 years. The fuel pump is a NOS replacement I put on it in the early 1980s. I ran regular gas in it when it was still available, a couple partial tanks of racing fuel just to see what it would do, then Unleaded, and then E10 ever since the local stations switched over to that. The old Flathead runs the same with any of them, and it is NOT running rich.... at least not on the idle circuit which was adjusted lean when set up in 1978. The main jets are stock, whatever size they are.... if they are rich, they haven't ever fouled the plugs, as they are still what I put in it in 1978 as well (and maybe about due for a change, but with what little I drive it, probably good for a few more years) The truck sets more than it's driven. Not counting the 14 year hibernation, it sets for 5 months from late fall to mid spring and then usually gets out once every other week for a short drive during the summer, setting for 2 weeks, driven 14 miles, setting for 2 weeks, driven 14 miles, setting for 2 weeks.............. and then setting for 5 months again. Year after year after year with E10 and a humid storage building.
