Radium Engineering Fuel Surge Tank for External Pumps (FST-Series)

The Radium Engineering Fuel Surge Tank (external-pump configuration) eliminates fuel starvation on hard cornering, braking, and acceleration by keeping a constant supply of fuel to the high-pressure pumps. This version is plumbed for externally mounted EFI pumps rather than housing them internally, and uses a machined, anodized aluminum canister with O-ring-sealed billet caps and AN fittings. Compatible with E85 and other fuels. A universal solution for forced-induction and high-demand builds. Pumps not included.
