Radium Engineering Fuel Surge Tank Dual Pumps

from 669.95

A fuel surge tank (FST) is designed to prevent fuel starvation to the engine on vehicles with inadequate fuel tank baffling. The FST fuel pump(s) directly feed the fuel rail(s). The volume of fuel inside the surge tank acts as a buffer to always keep the FST pump supplied with fuel. This volume is maintained by the main fuel tank's pump as well as the fuel returning from the fuel pressure regulator. Excess fuel in the surge tank is returned back to the vehicle's main fuel tank.

The surge tank also provides a quick and easy way to upgade any standard fuel system without the need to modify the stock fuel tank or pump. This is an excellent fueling solution for vehicles installing large fuel demand power upgrades such as forced induction.

Radium Engineering Fuel Surge Tanks Include:

-Extruded and Machined Aluminum 1.5 Liter Canister 
-Bright Dipped Anodized and Laser Engraved Housing
-Removeable O-Ring Sealed Billet Aluminum Caps  
-6AN O-Ring Fittings
-Circular Bulkhead Electrical Connector with 24" Flying Leads
-Corrosive Resistant Stainless Steel Hardware

All pumps mount internally using gasoline, ethanol, and methanol resistant wiring. For dual-pump configurations, each pump is wired independently. All hoses are submersible and E85 safe. The pump outlet fitting(s) are available in -6AN male size only (shown in green). The other ports can be adapted to other -AN sizes using adapters (sold separately).

Additional Info

Mounting Hardware

The fuel surge tank can be mounted anywhere in the vehicle. However, mounting near collision prone areas, heat sources, or moving parts such as suspension components should be avoided. Note: All of the single pump FSTs listed above can be mounted anywhere from vertical to horizontal. However, the dual pump FSTs cannot be mounted completely horizontal because the pickups are on opposing sides of one another internally. Choose a bracket below that best fits the application.

Floor and Wall Mount - This bracket is laser cut from aluminum and powder coated black and can be mounted on the side or bottom of the surge tank.
