Radium Engineering "pumpless" FSTs were designed for users that already have a secondary external fuel pump. It provides a reservoir from which an external pump can draw from. It features a single or dual anodized PTFE pick-up tubes rather than an integrated internal fuel pump. These surge tanks are most effective when mounted vertically, however it can be tipped up to a 45 degree angle. Radium does not recommend mounting these surge tanks horizontally, as the pick-up may be prone to drawing in air pockets.
The High Volume fuel surge tank (HVFST) is an ideal option for very high flow external fuel pumps requiring a large reservoir and feed line. It must be mounted as near vertical as possible. A mounting bracket is not needed with the HVFST.
All external pump fuel surge tanks require a "lift pump" to supply them with fuel. Excess fuel is then routed back to the OEM fuel tank or fuel cell. The pump feeding the engine, then draws it's fuel from the surge tank, with excess returning from the regulator back to the surge tank.
