Radium Standard Single Pump FST Fuel Surge Tank

Radium Standard Single Pump FST Fuel Surge Tank

Application: Universal
Part Type: Single pump fuel surge tank (FST)
Part Number: 20-0960

A fuel surge tank keeps the engine supplied on vehicles with poor fuel tank baffling, and can upgrade a standard fuel system without modifying the stock tank or pump – ideal for high-demand builds such as forced induction. The fuel held in the surge tank buffers the internal pump, while the main tank pump and the regulator return keep it full and excess fuel overflows back to the main tank.

The Radium single pump FST uses a 1.5 litre extruded, anodised aluminium canister with removable O-ring sealed billet caps. The internal pump feeds the rail through a green 6AN outlet, and three interchangeable black 6AN ORB ports handle the lift pump inlet, overflow to the main tank and regulator return, with an internal deflector to reduce foaming and aeration.
