Evo 123 - AEM - 340LPH In-Tank Fuel Pump (E85 Compatible)
High-flow fuel for big-power builds
The AEM 340LPH High Flow In-Tank Fuel Pump delivers the fuel volume your 4G63T needs to support larger injectors and higher boost. Built to resist the low-lubricity characteristics of ethanol and methanol, it is tested to run on E85 and pump gas alike, making it a strong upgrade for flex-fuel and high-horsepower Evo builds. Its offset inlet design eases installation in the factory in-tank location.

Why it matters on your Evo 1-3
The factory fuel pump runs out of headroom quickly once you raise boost, fit bigger injectors, or move to E85. Upgrading to a high-flow in-tank pump keeps fuel pressure stable at high RPM and load, protecting your 4G63T from running lean and giving you the supply needed to chase real power gains.
Fitment
Mitsubishi Lancer Evolution I, II and III (CD9A / CE9A), 1992 to 1995. High-flow in-tank fuel pump for the AWD 4G63T fuel system.
