Radium - Fuel Surge Tank Install Kit, Focus EcoBoost

This comprehensive installation kit includes everything needed to install a Radium fuel surge tank (FST-R) in a 2013+ Focus ST and 2015+ Focus RS. The surge tank itself is not included with this kit and must be purchased separately. You can order it from the checkboxes on the right.

The fuel pump inside the surge tank is used to replace and mimic the OEM fuel supply line and feed the OEM HPFP. The pump is protected from fuel starvation as the OEM low pressure fuel pump is redirected to supply fuel to the FST. Overflow fuel returns back into the OEM fuel filler hose with an included billet adapter. The integrated regulator on the FSTR-RA can be vacuum referenced if 1:1 fuel pressure is required or ran static to mimic the stock system.

The MK3 Ford Focus install kit locates the FSTR-RA in a collision-safe area under the vehicle, in front of the rear bumper support. The anodized aluminum bracket solidly mounts to OEM mounting points. Heat tape is included to reflect unwanted heat from the exhaust system, as shown.

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