Aeromotive 18401 Gen II Stealth Fuel Tank 1968-1969 Oldsmobile Cutlass & Buick Skylark 340lph

The Aeromotive 18401 Gen II Stealth Fuel Tank is a direct drop-in replacement fuel tank engineered specifically for 1968–1969 Oldsmobile Cutlass and Buick Skylark applications. Designed for high-performance street and strip builds, this tank integrates Aeromotive's proven in-tank fuel pump technology into an OEM-style enclosure—eliminating the need for external pumps, unsightly fuel lines, and additional mounting hardware.

The Gen II Stealth design features a fully baffled sump that keeps the in-tank pump fed under hard acceleration, cornering, and braking, making it ideal for performance and modified vehicles. The integrated 340 LPH (liters per hour) fuel pump delivers more than enough flow capacity to support naturally aspirated and forced induction builds well beyond 600 horsepower at the crank.

Key Features:

• 340 LPH pump flow rate — supports high-horsepower naturally aspirated and forced induction applications
• Gen II baffled sump design — maintains consistent fuel delivery under hard acceleration, braking, and cornering
• Direct OEM fit — replaces the factory fuel tank on 1968–1969 Oldsmobile Cutlass and Buick Skylark without modification
• Integrated stealth design — conceals high-performance pump hardware inside the stock-appearing tank
• Compatible with gasoline and E85 — internal components rated for ethanol-blended fuels
• Pre-assembled and ready to install — pump, sending unit, and baffled sump included
• Corrosion-resistant construction — durable tank materials suited for long-term performance use

The Aeromotive 18401 is the ideal solution for classic muscle car builders who want serious fuel system performance without sacrificing the clean, factory look of the original fuel tank. Whether building a weekend cruiser or a full-race street machine, this Gen II Stealth tank delivers reliable, high-volume fuel supply right out of the box.
