The compatibility of stainless steel with methanol is supported by research. Studies have examined the localized corrosion behaviour of various stainless steel alloys, including Type 304L and Type 316, when exposed to methanol/lithium chloride solutions with different water contents. These studies provide insights into the conditions under which stainless steel can withstand corrosion in methanolic solutions.
Flex fuel injectors made of stainless steel can handle up to 100 psi, making them suitable for high-performance applications. Additionally, these injectors are compatible with ethanol, which is often present in modern fuel blends. By using a test kit, you can determine the ethanol content in your fuel to ensure it falls within the acceptable range.
When considering methanol fuel injectors, it is important to prioritize safety and compatibility. Flex fuel injectors made of stainless steel offer a durable option that can withstand the demands of methanol fuel while also accommodating ethanol blends. Proper maintenance and monitoring of fuel composition are crucial to ensure the longevity and optimal performance of your injectors.

Deka 220s injectors are methanol-compatible and have stainless internals
When it comes to methanol fuel, the injectors you choose are crucial. Methanol is an effective fuel option, but it requires compatible injectors to ensure optimal performance and avoid potential issues. In this regard, Deka 220s injectors stand out as an excellent choice for several reasons.
Firstly, Deka 220s injectors are specifically designed to be methanol-compatible. This compatibility is essential because methanol has different properties than traditional fuels, and using the wrong injectors can lead to performance issues or even damage. By choosing Deka 220s, you can be confident that they are engineered to work effectively with methanol, ensuring efficient fuel delivery and minimizing the risk of problems.
Another advantage of Deka 220s injectors is their stainless internals. Methanol is known to be corrosive to certain materials, such as aluminium. Stainless steel, on the other hand, is highly resistant to corrosion from methanol. By opting for Deka 220s with stainless internals, you eliminate the worry of corrosion, extending the lifespan of your injectors and maintaining the integrity of your fuel system.
The choice of injector material is critical when dealing with methanol. While stainless steel is an excellent option, other materials may not fare as well. For example, aluminium is typically advised against when using methanol. This is because methanol can corrode aluminium fittings and fuel rails over time, leading to potential leaks and other issues. By opting for stainless steel internals, Deka 220s injectors offer enhanced durability and compatibility with methanol fuel.
Additionally, Deka 220s injectors offer a robust and reliable performance. With their stainless internals, these injectors are designed to withstand the demands of methanol fuel injection.

Fuel injectors can be used for water/methanol injection but are liable to corrode
Fuel injectors can be used for water/methanol injection. However, they are liable to corrode when exposed to this mixture. This is because water immediately vaporizes and turns into steam when it passes through an injector, and because this occurs at high pressure, it will eventually damage the injector tips.
The original water/methanol injection system used in WW2 German aircraft (MW50) used water, methanol, and 0.5% anti-corrosion oil. This anti-corrosion additive may allow the use of standard injectors. Mechanical injectors with a lower pop pressure, such as those for petrol engines, may also be used.
Some fuel injectors are better suited to methanol fuel than others. For example, the Bosch 220lb CNG injector is known for its reliability, and the Deka 220s and 225s are also reliable options, albeit more expensive. Holley injectors have been known to stick when used with methanol, and some users have had to flush them after every race to prevent this.
To prevent corrosion and other issues caused by water contamination, it is important to maintain fuel quality. Ideally, the water content in fuel should be well under 0.5% by volume. Above that level, injector life is reduced by about half.
