I think these are good pictures of what ethanol in our gas does.
It is see through but also has very fine holes.

Any one agree?

I only run non ethanol gas in my equipment. It costs about .80 more a gallon but it gives me piece of mind , and I don't mow a lot 3.5 acres so it don't hurt my wallet like if I was cutting 30 lawns a week.
 
been running ethanol since it came out. NEVER had an ounce of trouble. Keep it in a sealed container, and keep it fresh. Gas and E-10 are formulated for winter and Summer, just like Diesel Fuel. I have a 30 year old JD 180 with a Kawasiki and just had the carb checked and the tech said it was like new.
 
That is a prime example of moisture getting into your fuel. Ethanol is alcohol, alcohol attracts moisture, moisture attracts corrosion, corrosion puts money in my pocket.

I will ask you the same thing I have asked others.

How do you know ethanol did that? What test have you done to prove it?

My guess is your not sure how or why it happened so blame ethanol.
 
Know that it is caused by moisture. Don't really know how the moisture got in there, unless it was carried by the fuel. Read my other post and draw your own conclusion.
 
Another possibility... Under that diaphram is a tiny hole to allow the diaphram to move. Something could have entered through that hole and did the damage notice how its around the edges instead of the middle. If it was from ethonol sitting it would be in the center more no? Now if something being water or debris the gas sitting in the diaphram would be more heavy in the center and pushing whatever got in to the edge..

Whatever

Damn good question! I just pickup a non-running mower. As I took it part i found
this diaphragm. Not the frist one like that. The tank was rusty.

Our gas is refined in Oakland, Calif. and piped up here. I have never heard of any
non-ethanol gas around here.
Just saying.....
