Running ethanol requires larger injectors, and certainly a stronger fuel pump. This is the AEM E-85 High Flow In-Tank Fuel Pump. This particular fuel pump flows 320 liters per hour and is strong enough to support fuel systems that are employing larger injectors with increased fuel pressure required to run ethanol. The AEM E-85 Hi-Flow Fuel Pump is compact in size to make installation straightforward.
Included with the fuel pump will be the wiring harness, pre-filter, as well as the O-rings.
