Dual Pump Add-On for Mid Chevrolet Corvette 03-13 Radium Engineering - USA-RAD-20-0937 - 20-0937 DUAL PUMP ADD-ON COMPATIBILITY*Mid 2003-2013 Chevrolet Corvette*Compatible with vehicles after VIN 35114930 (manufactured November 2002). OVERVIEW This is a dual pump add-on to the fuel hanger listed above. It includes another "independent" collector specific for pump 2. The architecture of the Corvette fuel tank is very unique. Because the opening is so small, 2 pumps cannot fit through at the same time. Each pump is sent into the tank one by one. The use of SAE quick connectors makes the installation process much easier. Both fuel pumps outlets merge into the single 10AN ORB outlet of the CNC machined fuel hat. And because of the check valves on the pump outlets, fuel pump staging is permitted.  COMPATIBLE FUEL PUMPS Choosing the best fuel pump is based on the expected engine power output, fuel type (gasoline, E85, etc.), and fuel pressure.
