Why is ethanol cheaper than gasoline?
Because ethanol costs less than gasoline due it being 100% domestically produced. It also has to do with the octane additives required to make up the lack of ethanol in the fuel. You need more chemicals like toluene or xylene to meet octane when ethanol is removed. And since there are more aggressive aromatics there is more risk of premature wear to your fuel systems. Just a friendly warning because after doing the research on material science, ethanol is more compatible with more materials than the additives in gasoline are.
How much water can an E10 hold?
E10 for instance, can hold up to 4 teaspoons per gallon before any separation or problem occurs. The more ethanol you have, the more water you could hold without issue. However, if you have more than 4 teaspoons per gallon from condensation you have a bigger problem like the fuel cell cap being faulty.
Does ethanol draw moisture out of the air?
"“Pot metal” and other metal components are not damaged by the ethanol but rather by the moisture that pure ethanol draws out of the air."#N#It doesn't draw it out of the air, especially not from the inside of a fuel cell. What causes water contamination in a fuel cell is the condensation that does and can form in the empty portion of the tank itself and it occurs no matter what fuel you use. With gasoline, the water instantly separates and creates a layer of water, with ethanol blends, it will absorb up to a certain amount. E10 for instance, can hold up to 4 teaspoons per gallon before any separation or problem occurs. The more ethanol you have, the more water you could hold without issue. However, if you have more than 4 teaspoons per gallon from condensation you have a bigger problem like the fuel cell cap being faulty. To say that ethanol can absorb moisture "out of the air" is incorrect and is not how the hygroscopic ability works. I have used the Karl Fisher titration method to test fresh 200 proof ethanol from the plant to see if it indeed can absorb moisture out of the air, it cannot. The 200 proof ethanol is actually 199 and change and holds about 1% moisture. I let an open beaker sit all night on a night shift and tested it and it still sat around the 1% mark.#N#You also mentioned that refiners should add corrosion inhibitors, this is done both at the ethanol plant as well as the oil refiner to finished products. Usually products like CorrPro 656 are used.
Is polyurethane compatible with ethanol?
Polyurethane based materials are not compatible with the various additives in gasoline (aromatics such as toluene, xylene, and benzene) nor is it compatible with ethanol. Stay away from using the "blue" for fuel purposes. Material compatibility charts from companies like Mykin or Cole Parmer are very beneficial when selecting materials for fuel system use. Remember to check the various chemicals present in today's gasoline, not just ethanol. If you aren't sure what is in your local gasoline, request an SDS sheet from your local station as it will give a breakdown of their fuel. What many do not know is that ethanol is actually more compatible with more materials used in fuel systems than the individual chemicals that make up today's reformulated gasoline are.
Is neoprene hose good for gasoline?
Just wanted to clarify. Neoprene fuel hose consists of a Nitril inner tube and a Neoprene outer covering. Neoprene in itself is not a good choice for compatability with gasoline.
Can you distill ethanol to 95%?
You can only distill ethanol to 95% purity; try to get above that and the molecular attractive forces between water and ethanol are stronger than the temp difference on distillation, so the corn plants must run the 95% stuff thru a molecular sieve to get the last 5% of water out - therein lies the rub.

last time I bought hose at AZ, they gave me the fuel injection stuff. When I questioned them, they said that was the only kind they carried. Not sure if it was a store decision or company wide, but probably a good move on their part.

Started in 1967, it regulates certain emissions related parts. Some fuel hoses have “CARB No.” printed on the side. This will be followed by a sequence of letters and numbers that indicate the hose can be used in the state of California.
Do fuel injection clamps work?
A clamp that is too large will not evenly seal the fuel hose to the line. The second consideration is the type of clamp. Worm gear clamps may work for low-pressure applications. But, for fuel injection applications, you need clamps that are specifically designed to handle the pressure and not damage the outer layer of the fuel hose.
Is a fuel hose universal?
Fuel hoses are not universal. Outside of the dimensional requirements, fuel hoses have requirements for permeation, pressure and the type of fuel they can carry. This can get even more confusing when you start looking at the lettering on the side of the hose.
