Installation Checklist
The following list of steps is an overview of the installation process. A complete and more detailed list of each
step including optional peripherals is defined later in this document.
q
Install Tank
oThe tank must be mounted such that it is below the injection point. Failure to do so may
lead to fluid leaking into the intake tract due to gravity or siphoning, which may result in
engine damage.
oFasten with 4 of the 8 supplied #8 sheet metal screws along with the 4 large washers or the
5/16-18 bolts and Nylock nuts.
q
Install Pump
oSelect suitable location for pump near and below the lowest fluid level of tank.
oFasten with 4 of the #8 sheet metal screws along with the 4 small washers or the #8-32 bolts
and Nylock nuts.
oCut supplied nylon hose with a sharp razor blade and install from tank to pump.
q
Install Controller
oDisconnect ground side of battery during electronic installation.
oFind suitable location for controller inside driver’s compartment.
oFind location in driver’s field of view and install external LED.
oFollow the wire diagram and connect wires from supplied wire harness.
oConnect boost hose line to both controller and manifold pressure.
q
Flush Tank
oConnect the remainder of hose to pump. (DO NOT CONNECT NOZZLE.)
oFill tank with water. (AEM recommends using distilled water.)
oTurn on ignition power (Arm switch) to power on controller.
oUse TEST button on controller to flush the tank into a separate container. Press and hold to
activate the test function. (Repeat several times to completely flush system.)
oDrain tank and proceed to next step.
q
Connect Nozzle to System
oSelect nozzle and connect to nylon hose.
oFill tank with water.
oUse TEST button on controller to test complete system.
q
System Check
oWhile pushing the TEST button, ensure that no errors are reported and that the system is
producing a gradually increasing flow out of the nozzle.
oThis may require pressing the TEST button multiple times to purge the system.
oDrain tank and fill with desired water/methanol mixture.
oDO NOT use a hydrocarbon fuel. Water and methanol are the only supported fluids.
q
Install Nozzle
oThe nozzle must be mounted such that it is above the tank. Failure to do so may lead to
fluid leaking into the intake tract due to gravity or siphoning, which may result in engine
damage.
oFind a suitable location to install nozzle. Nozzle must be mounted before the throttle plate.
Nozzle should also be mounted after the MAF sensor, if present. Nozzle must also be mounted
after any intercoolers.
oInstall nozzle, following instructions for modifying intake to accept the nozzle.
oCut and install nylon hose from pump to nozzle. Ensure that the hose is not resting, near, or
running on any moving or “hot” parts.
q
Tune Engine
oEngine tuning is usually required in order to maximize potential power gain.
