WHAT IT DOES The AEM Water/Methanol Check Valve kit works with any 1/4 OD water/water injection tubing and is typically used used as a replacement or upgrade part for nearly any water/methanol injection kit. PRODUCT FEATURES * Universal 1/4 OD Injection Tubing size   *15psi Crack Pressure Legal in California only for racing vehicles which may never be used upon a highway. Note: FOR OPTIMUM RESULTS ALL WATER/METHANOL INJECTION SYSTEMS AND GAUGES SHOULD BE RUN WITH AN AEM INLINE FILTER (AEM PART #30-3003) Important Safety Notice Regarding Methanol AEM strongly recommends that users never exceed a 50% methanol concentration when using any AEM Water Methanol system or component. All AEM Water/Meth injection systems and components (pump lines fittings filter flow sensor tank and nozzles) are 100% chemically compatible with methanol. However for safety reasons we strongly recommend that users never use more than a 50% methanol concentration in our systems. Methanol is a toxic and highly flammable chemical. 100% Methanol ignites easily and burns vigorously with an almost undetectable flame. Methanol can be absorbed through the skin and even x-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% methanol concentrations are x-small if they exist at all. However the safety issues are very real and far out weigh any perceived benefit of running high concentrations of methanol. WARNING! Improper installation and/or adjustment of this product can result in major engine/vehicle damage.
