Show original supplier description

The AEM 340LPH E85-Compatible High Flow In-Tank Fuel Pump (PN 50-1215) is engineered for demanding, high-performance applications, including naturally aspirated and forced induction EFI vehicles. Its robust internal construction is specifically designed to withstand the low lubricity of ethanol and methanol fuels, ensuring reliable operation with ethanol up to E100, methanol up to M100, and all gasoline types. This pump boasts a flow rate of 340 liters per hour (lph) at 40 PSI and features a compact 39mm diameter, making it suitable for a wide range of applications. The offset inlet design simplifies installation. The kit includes the fuel pump, a pre-filter, internal fuel hose, clamps, an end cap, and a rubber buffer sleeve. Important considerations include that this product is not CARB legal and is not for sale in California. The product instructions also note that the vehicle's factory fuel pump wiring may not be adequate for the current draw of AEM's High Flow Fuel Pumps, and proper wiring is crucial. Polarity of the electrical plug must be confirmed and corrected if necessary using the supplied plug. While the pump shares the same physical size as many OEM pumps, it may not be appropriate for all specific applications, and users are strongly advised to check fuel pump sizing for their vehicle before purchase. AEM does not approve of or guarantee performance if the fuel tank is modified to accommodate the pump.
