classic case of ethanol poisioning

Re: classic case of ethanol poisioning

Are we talking fuel lines to the motor or inside the motor? If they're the ones inside, where does on get the correct size, in bulk, that's ethanol resistant? I just had my carbs. rebuild and would like them to stay clean!

Re: classic case of ethanol poisioning

Is there a way to identify alcohol resistant fuel line from the printing on the line?

Hi All,

Those are some crazy tricks to clean out your carbs. Question; what happend to the old reliable 'carb dip'? For about $20 you can buy a gallon of it in a paint can with a strainer tray. An overnight dip and scalding hot rinse has never let me down on non marine applications; I don't see why it would not work in Tashasdaddys case.

Careful with leaving a Marine carb in the dip too long, 20 minutes is PLENTY if the chemical is near new.

Marine carbs are hard anodized inside and out, dip eats away the crud, but it also eats away the anodizing, leaving nice clean aluminum. The problem with that is moisture, in the air and in the alcoholl in the fuel, causes that nice shiny aluminum to corrode. Doesn't hurt a thing outside but the appearance, INSIDE, well, that's a whole nother reason to take it apart and clean it AGAIN, and AGAIN, and AGAIN.

Soak them just long enough to do the job, no overnighters.

Re: classic case of ethanol poisioning

Yikes! This I did not know and, well, I may be in trouble. I use dip for its intended use and often let it soak overnight. Hay.....arnt all carbs anodized?

Re: classic case of ethanol poisioning

and what is "anodized" if not "corroded"?

Re: classic case of ethanol poisioning

TD...do you recommend changing all lines from tank to carb with alcohol-resistant lines, or just from the quick-connect to the carb? As another post asked...is the alcohol-resistant line marked in any way? Don't want to sludge up my Big Twin carbs...would a soak in E10 dissolve this stuff, maybe use E10 in a parts cleaner?

Re: classic case of ethanol poisioning

i recommend that all lines be alcohol resistant. they are marked alcohol resistant.
i am not promoting this product, just an example. http://www.tempoproducts.com/products.php?action=view&prod_id=5&tier=items

you can get the internal lines at auto parts or marine store. i have only found the 5/32 line at the dealers.

Re: classic case of ethanol poisioning

another interesting feature of ethanol in gas is its ability to clean it will remove all those old layers of varnish on everything and deposit it in the filter plugging it and anything after the filter ends up in the carb or injector making life miserable

Note that you should use A1 or A2 rated lines inside the engine cowling, especially between the fuel pump and engine.

Re: classic case of ethanol poisioning

All of my fuel lines with primer bulb are labeled alcohol resistant, but I'll be watching them now. Replacing the fuel lines under the cowl on five motors is what I dread, but it's in the plan...can't find ethanol-free gas in my area.

Re: classic case of ethanol poisioning

Great discussion going but the carbs posted look more like it set a while and ethanol gas evaporated and oil formed a gum. 99% of the carbs I repair that have ethanol damage have a white or yellow crystalline debris in them. Also the lines are swollen internally and you find small black carbon looking specks in bowls from lines degrading.

Re: classic case of ethanol poisioning

I just rebuilt my carbs and the bowls looked worse than the pics TD posted! Both bowls were completely covered with varnish, but I did get them cleaned out - including all jets and orifices. I've replaced all of the fuel lines including the primer bulb. Are all new hoses (incl from dealers) alcohol resistant, or must they be special ordered? I don't see the words on the gray Johnson lines, and can't see the small black hose connecting the two carbs well enough to read anything...

Re: classic case of ethanol poisioning

I thought you could look at the pump at the gas station to see if and how much ethanol was in a given sellers gas but that is not true. I was using brand X gas because I could see no such disclaimers of ethanol content posted on the pump. Yesterday a race buddy of mine dropped his test meter into my gas can and to my dismay I was running fuel that would prove disqualifying.

So?this begs the question; does anybody know where one can find the scoop on what is required state for state and where the pure gas can be found. I have heard that farmers and marinas are exempt from the ethanol rule but I would really like to find the reference documents to refer to.

Anyone know???

Re: classic case of ethanol poisioning

I have a marina near by that sells 'Marine Grade Gas' that advertizes 'no ethenol' and that it remains stable for a year without fuel stabilizers. I am pretty sure they are associated with Marathon. They do charge an extra buck a gallon, however, over the pump gas I put in the cars.

Around here only about 1/2 the area is under EPA mandate. For the first couple of years you could go to a non-mandated county and buy all the regular gas you wanted.

Since then everything has gone to e-10. Most the marinas carry E-10 as well. Makes it easier on the distributors. They don't have to fomualte different fuels for different areas.

Re: classic case of ethanol poisioning

Only 2 marinas out of 6 on Old Hickory sell E-10 and all get their gas from same distributer ...Parman oil.. I asked the driver one day and he has a blending unit on truck to add E-10. It depends on what customer wants and blended fuel is cheaper to purchase,

Re: classic case of ethanol poisioning

I just started going threw a 57 Evinrude and am going to be ordering a carb kit for it asap. Has anyone noticed a problem with the ethanol damaging the float? I am waiting to tear the carb apart until I have the kit here so I can do everything at once, so I haven't been able to take a look at mine. I'm just wondering if I should order one or not. Thanks.

Re: classic case of ethanol poisioning

I have heard that it eats up the varnish on the cork floats. Be sure to get a BRP kit with the new plastic float.

That's interesting. E10 means 10% Ethanol, so even if ethanol were FREE, not having it should only cost 10% more, so unless you are paying $10 a gallon at the other marinas, a buck a gallon is a pretty good mark up.
