AEM fuel pumps include a universal pre-filter which may not fit certain vehicle applications. Please refer to the OEM recommendations for filter replacement for your vehicle. Your vehicle's factory fuel pump wiring may not be adequate enough to handle the current draw of AEM's High Flow Fuel Pumps. Please refer to the Electrical Requirements section in the instructions document for proper wiring. It is imperative to ensure that the polarity of the electrical plug in your tank is correct for your pump if you choose to use it. If it is not correct, you can either re-pin it or use the supplied plug. Although AEM's High Flow Fuel Pumps are the same physical size as many OEM fuel pumps, they may not be appropriate for a specific application. It is imperative that you check the fuel pump sizing for your vehicle before purchasing an AEM High Flow Fuel Pump. AEM does not condone or approve of the modification of a tank to accommodate a High Flow Fuel Pump and cannot guarantee the pump's performance or operation if any modifications are made.
