39mm High Flow In-Tank EFI Fuel Pump

The AEM 50-1220 is an E85-compatible, high-flow, in-tank fuel pump engineered to meet the demands of high-performance naturally aspirated and forced induction EFI vehicles. Its robust internal construction is specifically designed to withstand the lower lubricity characteristics of ethanol and methanol fuels, with testing confirming compatibility with ethanol up to E100, methanol up to M100, and all types of gasoline. The pump boasts a compact body measuring 39mm in diameter and 65mm in length, making it suitable for universal applications with tight fuel tank tolerances. The offset inlet design further simplifies installation. Each AEM 50-1220 fuel pump is rigorously tested to flow 340 liters per hour (LPH) at 40 PSI before being packaged for sale. The unit includes a wiring harness, pre-filter, and O-rings, with the recommendation to use the stock isolator sleeve. It is important to note that while the AEM High Flow Fuel Pumps share physical dimensions with many OEM pumps, they may not be a direct fit for every application. Buyers must verify the fuel pump sizing for their specific vehicle before purchase. Additionally, the included universal pre-filter may not be compatible with all vehicle applications, and users should consult OEM recommendations for filter replacement. The factory fuel pump wiring may also be insufficient for the current draw of this high-flow pump, necessitating a review of the Electrical Requirements section in the installation instructions for proper wiring. AEM does not endorse or approve of any modifications to the fuel tank to accommodate this pump and cannot guarantee performance or operation if such modifications are made.
