Radium Engineering Fuel Surge Tanks
Radium Engineering Fuel Surge Tanks in Australia
A fuel surge tank keeps a small, always-full supply of fuel at the main pump, so the engine doesn't go lean when fuel sloshes away from the pickup under hard cornering, braking or at low fuel levels. Radium Engineering makes single pump, multi-pump, regulated and fuel cell surge tanks, plus car-specific install kits and service parts.

Choosing the Right Part
Work out how many pumps you need first. One high-flow pump suits most street and track builds; big-power or E85 builds often need the MPFST or MPFST-R.
Decide where regulation happens. The FSTR RA and MPFST-R have a regulator built in; the others work with a separate fuel pressure regulator.
If there's an install kit for your car, start there, as it includes the brackets and plumbing for that chassis. Pumps are not always included, so read each listing.
Installation & What You'll Need
A surge tank needs a lift pump from the main tank, a feed and return to the surge tank, a high-pressure pump feeding the engine, and a vent or return back to the main tank. That means AN hose and fittings, pump wiring and a secure mount. Fuel system work should be done by a professional, with the system depressurised and away from ignition sources.
FAQ
Why fit a fuel surge tank?
Under hard cornering, braking or at low fuel levels, fuel moves away from the pickup in the main tank. A surge tank stays full and keeps feeding the engine pump, so fuel pressure doesn't drop.
Are pumps included?
It depends on the listing. Some tanks come with pumps and some are sold without, so check the title and description.
Do I need a separate fuel pressure regulator?
The FSTR RA and MPFST-R have one built in. The FST, MPFST and FCST-X are usually run with a separate regulator.
