AEM (30-3320) V2 Water/Methanol Injection Tank Kit - 5 Gallon Capacity Methanol is a toxic and highly flammable chemical; 100 percent Methanol ignites easily and burns vigorously with an almost undetectable flame Methanol can be absorbed through the skin and even small amounts can cause blindness or even death Using this fluid at high pressures, without dilution, in an under-hood environment with nylon lines and push-to-connect fittings is very unsafe The performance advantages of using greater than 50 percent methanol concentrations are small, if they exist at all However, the safety issues are very real and far outweigh any perceived benefit of running high concentrations of methanol
