AEM 340lph High Flow In-Tank Fuel Pump (Offset Inlet), 94-07 WRX/STI, Evo 4-9, Silvia/Skyline

AEM's 340LPH High Flow In-Tank Fuel Pump is designed for high performance naturally aspirated and forced induction EFI vehicles. It delivers reliable performance and high volumes of fuel flow for roughly half the cost of comparable performance fuel pumps.

The AEM 340LPH High Flow In-Tank Fuel Pump (PN 50-1000) flows 340 lph (84 gph) at 40 PSI and is capable of supporting over 1,000 HP at 43 PSI.* Please see the flow curves and current draw vs. fuel pressure graphs on the specs tab for more information.

This fuel pump is designed for in-tank mounting for use with gasoline and features a compact 39mm diameter that fits most applications. It has an offset inlet design that eases installations and includes a wiring harness, pre filter, internal fuel hose and clamps, end cap and rubber buffer sleeve. Every pump is tested to flow 340 lph at 40 PSI before it is packaged for sale.

Notes:

• 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. You can download a copy of the instructions from the BUY/INSTRUCTIONS tab on the product pages of our website.
• It is imperative to ensure that the polarity of the electrical plug in your tank is correct for you 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. You can consult the Vehicle Search function on our website to see whether a pump is recommended for your vehicle. The Vehicle Search function should be used as a reference only. 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.

Hard Wire Kit Option:

Get the most out of your new high flow fuel pump by ensuring it gets the voltage it needs. Old, compromised OE wiring can limit the voltage your fuel pump receives. A hardwire kit includes everything you need to safely, easily, and reliably wire your pump directly to your battery, ensuring no matter how hard you push your pump, your wiring will be up to the task. We especially recommend this kit for use in cars over 10 years old, cars making over 400whp, and cars which were originally not designed for high horsepower.
