Modern Fuel Chemistry & Its Affect on Fuel Hose
Life is still pretty good, but choosing the right fuel hose has gotten a bit more complicated. The main reason why is the makeup of modern fuels. For example, ethanol blends and additives like benzene and toluene are often used to increase the octane level of gasoline—but will also suck the oils out of your rubber hose.
How to Tell the Difference Between the Types of Fuel Hose
You can’t tell the difference between fuel hoses simply by looking at them. You’ve got to read the hose specs, often printed on the hose itself. (Image/ Dayco)
SAE 30R6 and 30R7 Hoses
These hoses were the industry standards for decades. SAE 30R6 and 30R7 hoses were designed for fuel systems rated at 50 PSI or less of working pressure like carburetors and TBI fuel injection. The hoses have a nitrile rubber inner liner reinforced with single-ply braided cord and a neoprene rubber cover.

What causes water contamination in fuel cells?
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.
What is fuel line?
Fuel line is a petroleum-resistant nitrile tube with a covering that resists weathering, ozone and heat and can be used for ethanol-laced fuels and diesel fuel. It should, however, not be used on coolant systems, oil systems or fuel-injection systems that produce pressures higher than 50 psi.
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.
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.
Does tygon rubber turn brown?
Tygon is available in short sections or on a large roll and can be quite expensive, but it will outlast the standard vinyl by many years and does not turn brown and brittle after extended use, as vinyl tubing often does. Standard rubber vacuum or heater hose should never be used in fuel applications.
