This comprehensive installation kit includes everything needed to install a Radium fuel surge tank with a single 39mm fuel pump in a Porsche (996) 911 Turbo. To purchase the physical Radium Engineering FST, click HERE. Here is a informative video on how a Radium Fuel Surge Tank (FST) works:

The Porsche 996 Turbo install kit locates the FST in a collision-safe area of the trunk, centered in front of the fuel tank allowing the majority of the trunk to be useable. The anodized aluminum bracket solidly mounts to the OEM fuel pump cover studs and an aluminum replacement fuel pump cover is included.

The OEM fuel pump hanger utilizes a sensitive dual venturi pump system that cannot be easily altered. This FST install kit includes a specifically designed FST orifice that keeps the necessary pressure in the OEM venturi system. For increased flow to the FST, this Porsche 996 fuel pump upgrade HERE, is recommended.

To adapt the PTFE hoses to the OEM Porsche lines, Radium has designed special low profile SAE quick disconnect fittings that are provided in the kit.

Also included are wiring components with flying leads featuring Raychem solderless butt splices, and a weatherproof fuse and relay to drive the FST's fuel pump. Wiring is very simple and takes less than 30 minutes to assemble. No soldering is required. 

Included are 4 PTFE hoses which are cut to length and preassembled. Supplied in -6AN size only.


-Preassembled 3/8" (-6AN) PTFE Hoses 
-Aluminum Mounting Bracket
-Aluminum Pump Hanger Cover
-AN and OEM Style Adapter Fittings
-Stainless Steel Hardware  
-Wiring Components with Relay and Fuse
-Solderless Heat Shrink Connectors  


If a Radium Engineering dual internal pump FST is required, this can be achieved. However, the plumbing and electrical in this kit was designed for 1 pump. Simply choose a FST with dual pumps HERE to use with this Porsche 996 TT install kit. Also pickup a DIY harness HERE as well for the electrical required to drive the second FST pump. Lastly, you will need to plumb a second hose from the FST to the fuel rail. These PTFE hoses HERE can be helpful.
