Aeromotive 18688 Phantom 340 Stealth In-Tank Fuel System

The Aeromotive Phantom 340 Stealth Fuel System (Part #18688) is an in-tank fuel pump system engineered for high-performance street and race vehicles that demand reliable, high-volume fuel delivery without the need for a custom fuel cell. The Phantom system utilizes Aeromotive's proven 340 Stealth fuel pump, delivering up to 340 liters per hour (LPH) of fuel flow — capable of supporting naturally aspirated and forced-induction engines well beyond 700 horsepower.

Unlike conventional external pump setups, the Phantom system mounts entirely inside your factory fuel tank, preserving a clean engine bay appearance and maintaining near-silent operation. The self-contained design includes a universal drop-in sump assembly that can be trimmed and fitted to most OEM steel or plastic fuel tanks, eliminating the need for cutting or welding.

Key Features:

• 340 LPH flow rating — supports up to 700+ HP naturally aspirated or forced induction applications
• In-tank, stealth-mount design keeps the pump hidden and reduces noise
• Universal sump assembly trims to fit most OEM steel or plastic fuel tanks
• Compatible with gasoline, E85, and alcohol-based fuels
• Operates at pressures up to 65 PSI — suitable for both carbureted and fuel-injected applications
• Includes pump, sump, pre-filter, outlet filter/regulator assembly, and all necessary hardware
• No cutting or welding of the factory fuel tank required
• Brushless motor design for extended service life and consistent performance

The Aeromotive 18688 Phantom 340 Stealth Fuel System is the ideal upgrade for enthusiasts looking to maximize fuel delivery potential while retaining a factory-style installation. Designed and manufactured in the USA, this system reflects Aeromotive's commitment to precision engineering and performance reliability.
