Aeromotive 340 Stealth Fuel Pump (Offset Inlet, Inline)

NOTE: the polarity of this pump is reverse of the Walboro255 and many others.  Please check your wiring during installation!

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. (to find your vehicle, see the applications guide below)

What sets the 340 Stealth Pump apart is its superior flow throughout a wide pressure range. Compared to a typical 255 lph pump at 40 psi, the 340 boasts 340 lph at the same pressure. 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 a 255 lph is applicable.
• Offset Inlet, In-line with outlet
• Includes universal filter sock – may not fit in some applications (see OEM filter replacement recommendations)
• Designed for in-tank use only
• Can be used in carbureted or EFI applications
• Turbine pump mechanism increases durability and can be used in pulse modulated applications.
