This product is to be used with one of the fuel hangers above. It is recommended to use a single pump hanger to feed the surge tank. The surge tank can then be equipped with one or two fuel pumps to feed the engine. 

The Radium Engineering FHST (fuel hanger surge tank) add-on is the ultimate solution for fuel starvation issues. Due to the saddle-bag style OEM fuel tank and insufficient baffling in late model Nissans, fuel slosh is common when driven aggressively. Unstable pressure resulting in a lean fuel mixture can cause engine damage. A stand-alone surge tank is an excellent device for eliminating fuel starvation issues, but installation can be complex. This add-on is a fully functional fuel surge tank mounted inside the OEM tank.
