The Aeromotive 340 Stealth Fuel Pump is a high-output, in-tank, electric fuel pump that fits most popular EFI applications. The Aeromotive 340 is a compact, lightweight pump that bolts into many existing hanger assemblies.

What sets the 340 Stealth Pump apart is its superior flow throughout a wide pressure range. Compared to other popular aftermarket pumps, at 40 psi the 340 boasts more than 340 lph. That's over 30% more flow. This pump is ideal for applications requiring more flow while retaining the factory lines and mounting provisions available in the Original Equipment (O.E.) configuration. The 340 is also perfect for use as a universal replacement for applications that require more flow to support forced air power adders such as turbo and supercharged applications.

Stock fitment evo IX? What is the WHP power rating on Pump gas?

 

The 11542 pump is stock fitment into an Evo IX ( https://www.extremepsi.com/store/pro...7&cat=0&page=1 ). It will generally support around 400whp although its very dependent on things like fuel type, injector size and fuel pressure.

If you're looking to go beyond that power level, we recommend the Walbro 450 which is semi-drop in. It does require some modification to the hanger to fit. https://www.extremepsi.com/store/pro...roductid=30208

 

I'm more worried about Fuel Pressure Regulator being over run. How is 400WHP a lot? I made 460WHP on a 255 LPH Walboro.

 

I wonder this too

 

I was looking into this pump and noticed there are some special notes for use on an evo in their application guide. Is there a reason for this?
