Radium Engineering Single Pump Fuel Surge Tank
£388.87
A fuel surge tank (FST) is designed to prevent starvation to the engine on vehicles with inadequate fuel tank baffling. The surge tank also provides a quick and easy way to upgrade any standard fuel system without the need to modify the stock fuel tank or pump. It is also an excellent fuelling solution for vehicles installing large fuel demand power upgrades such as forced induction.
HOW AN FST WORKS
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.

PLUMBING
All adapter fittings on top of the FST are 6AN (9/16″-18) male.
1. The internal FST pump directly feeds the fuel rail(s), through the green 6AN bulkhead fitting. The pump outlet fitting is available in -6AN male size only.
2. The 3 black (interchangeable) 6AN ORB fittings are used for the following.
a. Fuel entering the FST (from the lift pump)
b. Fuel overflowing and leaving the FST (to main tank)
c. Fuel returning from the fuel pressure regulator
NOTES:
1. An internal flow deflector prevents fuel foam and aeration on all 3 ports.
2. The pumps mount internally using tubing that is gasoline, ethanol, and methanol resistant.
3. The overflow to the main tank is a requirement on all installations. Tanks without return ports will need customization of the hanger top or filler neck to create a port for the overflow.
