E85 Compatible 340LPH High Flow In-Tank Fuel Pump by AEM

AEM’s 340LPH E85-Compatible High Flow In-Tank Fuel Pumps feature robust internal construction that is designed to withstand the low lubricity characteristics of ethanol and methanol fuels, and are tested to work with ethanol fuels up to E100, methanol fuels up to M100 and all types of gasoline. Its compact, short body design (65mm length) with mounting hooks also makes it ideal in universal applications that have fuel tanks with tight tolerances.

The AEM 340LPH E85-Compatible High Flow In-Tank Fuel Pump is designed for in-tank mounting on high performance naturally aspirated and forced induction vehicles. It features a compact 39mm diameter that fits most applications and an offset inlet design that eases installation.

The 340LPH E85-Compatible High Flow In-Tank fuel pump includes a wiring harness, pre filter and O-rings. Every AEM 340LPH E85-Compatible Fuel Pump is tested to flow 340 lph at 40 PSI before it is packaged for sale.

AEM High flow fuel pump

Had to modify the pump a bit for my 2009 Subaru Forester XT. The clips that hold the pump in the housing, on the new pump were a bit too wide. My Foresters pump housing had a cap on the bottom side of the pump to hold it in the housing, so luckily I didn't need the AEMs clips and i just cut them off flush. I should have got a pic of that part. Ill post what I have. Hopefully this helps someone else!

Fits perfect easy to install

Very straight forward. Pump works great! Note: You will hear the fuel pump prime when starting the car it’s pretty noise. Great quality! Everything to do the install is included. If your OE fuel pump has a fuel pump o-ring space (on the non filter end of the pump) you will have to reuse this when installing the new single o-ring attaching the pump to assembly.
