Radium Fuel Hanger Surge Tank - Nissan 350Z, G35, G37, Q50 (Walbro/AEM, Pumps Not Included)

The Radium Fuel Hanger Surge Tank drops into the OEM fuel tank of the Nissan 350Z and Infiniti G35/G37/Q50 to cure the fuel starvation these saddle-bag tanks suffer under hard cornering, building a fully functional anti-starvation surge tank inside the factory tank with no cutting or bending of sheet metal. It accepts one or two Walbro 255-style pumps (GSS342 or AEM 50-1200), which are sold separately, and ships with the fittings, external hose, pressure gauge, fuse, and relay needed to complete the install.
