The Aeromotive 340 Stealth In-Tank Fuel Pump is a high-output, compact, lightweight, in-tank, electric fuel pump that fits most popular EFI applications and bolts into most existing hanger assemblies. What sets the 340 Stealth Fuel Pump apart is its superior flow throughout a wide pressure range. Compared to a typical 255 at 40 psi, the 340 Stealth Fuel Pump boasts over 30% more flow. This pump is ideal for applications requiring more flow while retaining the factory wiring and mounting provisions available in the Original Equipment (O.E.) configuration. The 340 Stealth Fuel pump is also ideal for use as a universal replacement for applications that require more flow to support forced air power adders such as turbo and supercharged applications.
