A&A Dual Pump Fuel System - Late 2003 C5 & C6 Corvette (Excludes ZR1)
Fuel your high-horsepower build the right way with the A&A Dual Pump Fuel System, engineered for late 2003 (VIN #114931 and later) C5 and all C6 Corvettes (excluding ZR1). Designed with simplicity, power, and reliability in mind, this system supports 600 to over 1,000 RWHP while eliminating the need to drop the fuel tanks or drivetrain—saving you up to 10 hours of labor.
Featuring a dual in-line pump assembly housed in a single unit, this system provides a seamless one-in/one-out line design with pumps that can be staged to activate at specific boost levels. That means you get smooth fuel delivery under normal driving and the extra flow you need only when boost demands it. The result is a quiet, efficient, and high-capacity system ideal for street or race applications.
Each A&A system comes complete with preassembled stainless PTFE lines, dual alternator-fed hotwire harnesses, adjustable Hobbs switches, a polished return regulator, and all fittings and tools required for a clean, no-fabrication install. It’s fully E85 compatible and pressure-tested for leak-free reliability—ready to support your next big-power Corvette build.
Why Upgrade?
Factory fuel systems on late C5 and C6 Corvettes struggle to support serious power, especially under boost. Traditional in-tank upgrades can create excess heat, noise, and installation headaches. The A&A Dual Pump System solves all of these issues with an external, staged setup that runs quietly, stays cool, and installs easily. No tank drops, no cutting, no compromises—just the fueling capacity you need for 600–1,200 HP applications.
