Aeromotive Stealth Fuel Pump

Universal Fit for Most EFI and Carbureted Applications

Part #: 11540

Overview

The Aeromotive 340LPH Stealth Fuel Pump is a high-output, in-tank electric fuel pump engineered to deliver exceptional fuel flow for a wide range of electronic fuel injection (EFI) and carbureted systems. Designed to fit most popular EFI applications, this compact and lightweight pump easily bolts into many existing hanger assemblies, making it an ideal upgrade or replacement for enthusiasts seeking increased fuel delivery without extensive modifications.

What truly sets the Aeromotive 340 Stealth apart is its superior flow rate across a broad pressure range. At 40 psi, it delivers over 340 liters per hour (LPH), which is more than 30% higher flow compared to many other aftermarket pumps. This makes it perfect for vehicles requiring enhanced fuel supply to support higher horsepower builds, including forced induction setups such as turbocharged and supercharged engines.

Its universal compatibility and retention of factory fuel lines and mounting provisions allow for a seamless installation experience, maintaining the original equipment (O.E.) configuration while providing the performance needed for demanding applications.

Construction & Design

The Aeromotive 340 Stealth Fuel Pump is built with high-quality materials and precision engineering to withstand the rigors of high-performance fuel delivery. Its turbine-style pumping mechanism enhances durability and efficiency, reducing wear and extending service life. The pump’s OEM 39mm body size ensures compatibility with many factory fuel system components, allowing it to fit seamlessly into existing setups without requiring custom modifications.

Designed specifically for in-tank installation, the pump benefits from constant fuel immersion, which helps maintain cooler operating temperatures and reduces the risk of vapor lock. The included universal filter sock protects the pump from contaminants, although users should verify fitment with their specific OEM filter recommendations.

Installation & Fitment

The Aeromotive 340 Stealth Fuel Pump is engineered for straightforward installation in most vehicles where popular aftermarket pumps are applicable. It bolts directly into many existing fuel hanger assemblies, allowing users to retain factory fuel lines and mounting provisions. This plug-and-play approach minimizes installation time and complexity, making it accessible for both professional installers and experienced enthusiasts.

While the pump is designed for universal fitment, it is important to confirm compatibility with your vehicle’s fuel system and OEM filter requirements before installation. The included universal drop parts kit provides essential components such as wiring pigtail, rubber hose, clamps, and grommet to facilitate a secure and reliable setup.
