AEM’s heavy-duty 200 PSI recirculation-style water/methanol injection pump delivers performance, reliability and quiet operation. The pump’s internal bypass design eliminates erratic on and off switching/pulsing and ensures consistent fluid delivery. AEM’s water/methanol injection pump is manufactured with a Santoprene diaphragm and EPDM seals to withstand corrosion from alcohol fuel mixtures.

AEM strongly recommends that users never exceed a 50% methanol concentration when using any AEM Water Methanol system or component.

All AEM Water/Methanol 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 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 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.

The AEM Water/Methanol Injection Pump can be used as a replacement pump in most Water/methanol kits or as the base for the do-it-yourself specialist.

AEM’s recirculation-style pump offers improved performance, reliability and a much smoother, quieter operation when compared to older switched-style pumps. With the use of a new internal bypass design, AEM’s upgraded pump eliminates the erratic on and off switching/pulsing and ensures consistent fluid delivery for optimum performance. With durability and reliability in mind, AEM has designed the pump with a Santoprene diaphragm and EPDM seals to withstand the harshest of alcohol mixes.
