A&A Corvette C5 / C6 Dual Pump Fuel System | 1997–2013

A&A’s dual-pump secondary fuel system combines two pumps in a single housing with one inlet and outlet. Designed for staged activation at different boost levels, it allows the factory pump to handle normal driving while the supplemental system operates when needed.

System Features

• E85-compatible system
• Adjustable fuel pressure and pump activation boost levels
• Supplier-listed flow: 530 LPH / 140 GPH at 60 PSI
• Supplier-rated capacity: 1,200 HP at 60 PSI; actual support depends on fuel and application
• Preassembled stainless PTFE lines with stainless crimp sleeves, pressure checked by A&A
• Russell quick-connect fittings at the factory fuel rail and feed line
• Heat-shrunk connections and Weather Pack-style connectors

Included Components

• Dual pumps in a single housing and custom pump mounting brackets
• Preassembled stainless PTFE lines
• Two preassembled hotwire harnesses for alternator-direct power
• Two adjustable Hobbs switches
• Return regulator with polished mounting bracket
• Fuel filter and necessary fittings
• Fuel-line disconnect tool and fuel-tank drain hose

Fitment Options

• DPFS 97: supplier dropdown lists 1997–1999
• DPFS 00-02: supplier dropdown lists 2000–early 2003, up to VIN 114930
• DPFS 03-13: late 2003–2013, excluding C6 ZR1

The A&A C6 Dual Pump Fuel System is applicable for late 2003  (VIN # 114931 and later) C5 and all C6 models (excluding ZR1)

• The system comes with preassembled stainless PTFE lines, two preassembled hotwire harnesses for alternator direct power, two adjustable Hobbs switches, return regulator with polished mounting bracket, high capacity dual pumps, custom made pump mounting brackets, fuel line disconnect tool, drain hose to pump fuel from tank, filter and all necessary fittings. The system is E85 compatible.
• Our lines are assembled using a 10,000# hydraulic press with heavy duty Stainless Steel crimp sleeves. Each hose is pressure checked at our facility before shipment.
• Our pressure line snaps onto your factory fuel rail and factory fuel feed line with Russell quick connect fittings just like the OE lines. There is absolutely no fabrication of lines or fittings needed.
• Both the fuel pressure and the boost level at which the pumps turn on are  adjustable.* We heat shrink all our connections, use Weather Pack style connectors and high quality pressure switches for reliability.
• Pump flows 530 LPH or 140 GPH at 60 PSI fuel pressure.
• This system is rated at 1200 HP at 60 PSI. For horsepower levels above this, we can simply add a Boost A Pump, or even 2 Boost A Pumps for extremely high horsepower applications.
• The beauty of this system is that only the factory pump runs under most driving conditions. Running dual in tank pumps full time only serves to heat up the fuel and cause its own set of problems.
• When looking at a large in-tank solution from one of the big names, you’ll see a warning about hot fuel and the need to keep extra fuel in the tank to minimize heat damage.
• Those setups are also terribly annoying. Listening to a noisy fuel pump singing all the time will drive you nuts! Our system is seamless and quiet. You’ll never hear the pump as it only comes on under boost, when it’s needed.
