Aeromotive 340lph Fuel Pump




*Attention* This pump is an offset inlet with inline top outlet, the same as the Walbro 342 standard fitment


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 most 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
• 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.

SPECIAL NOTE, if you are installing these in an 92-00 Civic or 94-2000 Integra, please be forewarned that it appears the PLUG for power and ground on these pumps is REVERSE POLARITY from the stock wiring. When you or your installation facility install the pump, take note of this. ALSO, the sock that is included with the pump will not work for these same vehicles, and you will want to use the add-on option to include a Walbro 400-846 fuel pump install kit to place the sock in the factory location.
