FHST Add On for Nissan Pumps not Included Walbro GSS342 or AEM 50-1200 Radium Engineering - USA-RAD-20-0700 - 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.  FUEL PUMP INFORMATION Both brushed and brushless fuel pumps are compatible with the FHST Add-On. Fuel pumps are not provided but can be purchased from the links below.20-0701Walbro F90000267 E85Walbro F90000274 E85Walbro F90000285 E85Ti Automotive E5LM (brushless)20-0700Walbro GSS342 255lph AEM 50-1200 E85 ELECTRICAL External high current fuel pump wiring is provided for installing one FHST pump (1 relay, 1 fuse, and all associated wiring and hardware).
