About Us

To us, passion is defined by three generations of performance. Aeromotive is the by-product from generations of blood, sweat and tears that has shaped our knowledge and experience. Our commitment to develop the pinnacle of performance products comes from our history, our real world experiences and our passion. That’s why you will see us at the track, driving our cars, learning from our peers and living the industry we love. We believe that performance means reliability, longevity and durability. This is the philosophy we’ve built our company and our products on. Through the years, we have grown rapidly and are distancing ourselves because of our methodical, meticulous approach to deliver unrivaled performance with unmatched durability.

Product Description

Aeromotive Inc. is a true high performance aftermarket manufacturer specializing in fuel delivery and fuel delivery components. Utilizing aerospace tolerances and procedures, three generations of track experience, and a meticulous approach to engineering, Aeromotive Fuel Systems has become the absolute pinnacle of performance fuel delivery. Offset Inlet, inline with outlet, 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 mph. 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. Fits most vehicles where popular aftermarket pumps are applicable. P/N 11540 Includes: Pump, Universal Drop Parts Kit (Filter, Wiring Pigtail, Rubber Hose, (2) Clamps, Rubber Grommet).

    5.0 out of 5 stars Great pump. Installed inside factory sending unit.
    Reviewed in the United States on April 27, 2020
    Verified Purchase
    I want to start this by saying*A lot of vehicles will not show any results for a fuel pump by itself. Only full sending unit assemblies. A lot of times, you can still replace the fuel pump.* I installed this on a 2008 (built in early 2007) F350 6.8L v10. I replaced the original pump with a cheap one from O'riley's to get me back on the road..it only lasted a couple months. I only had the truck for a couple more months after installing this fuel pump, but it wasn't giving me any trouble at all. Installing this pump was pretty difficult, but I installed it in the factory fuel bowl/sending unit. I had to do quite a bit of trimming to the sending unit. In the end it had a *near* OEM look and performed 100% as expected on an otherwise stock application. If you are installing this in a factory sending unit, make sure you find out if yours has multiple screens and get them. And dont forget to replace the O-ring on top of your tank!

    Used this fuel pump with my supercharged LS3 swapped 1990 300zx. Literally drop in, stock lines and all, with the only other addition being an Aeromotive fuel pressure regulator. No issues, AFRs are solid at WOT, conservative setup with 6lbs of boost on 91 octane.

    5.0 out of 5 stars Quiet pump!
    Reviewed in Canada on September 11, 2019
    Verified Purchase
    Went from a walbro to this. It’s only been in for a couple weeks so I can’t attest to longevity but much much quieter pump, can barely hear it running when your listening for it. No problem putting out enough fuel for 550 rwhp. Only complaint is that their connecter is massively huge for a two wire connector, literally 8x the size of the walbro, and barely fit inside my basket. Hardwire is always an option.
