Radium Engineering – 2013-2018 Focus EcoBoost Fuel Surge Tank Install Kit

Radium Engineering – 2013-2018 Focus EcoBoost Fuel Surge Tank Install Kit

OVERVIEW

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.

INCLUDES

• Aluminum MK3 Focus FST Mounting Bracket
• Aluminum Push Lok -6AN Hose Ends
• AN and OEM Style Adapter Fittings
• Vapor Shield 3/8′ (-6AN) EFI Hose
• Wiring Components with Relay and Fuse
• Stainless Steel Hardware

NOTES

• As FST-R (Fuel Surge Tank-Regulated) is needed to go with this installation kit. See the options above.
• A means for adjusting the FST-R fuel pressure is needed. This can come from special OBDII software such as a COBB Access Port. Alternatively, Radium 20-0152 can be installed on the FSTR-RA outlet port.
• Depending on the flow rate of the fuel pump installed into the FST, a drop-in fuel pump upgrade may be required in the main tank. The main tank’s pump is responsible for keeping the surge tank full, and requires a pump that flows around 40% to 50% of what the surge tank pump flows. This is an estimate and will vary.

• COMPATIBILITY

  • 2013+ Ford Focus ST
  • 2015+ Ford Focus RS

ORDERING

This installation requires purchasing the install kit, the surge tank and the fuel pump for the surge tank separately. Many different fuel pumps can be installed into the surge tank and the available pump options from Radium directly are listed in the check boxes to the right.

To order a complete kit, select the install kit, the surge tank, and one fuel pump. To use a fuel pump other than what is listed, do not select a fuel pump from the checkboxes and order the desired fuel pump from another source.
