Description

The Radium Engineering Fuel Surge Tank Install Kit is a comprehensive installation package for fitting a Radium FST-R (Fuel Surge Tank - Regulated) to the MK3 Ford Focus ST and RS. The FST-R is sold separately. If auxiliary port injection is also required, consider the port injection FST kit 20-0366-00 instead.
The FST-R pump replaces and mimics the OEM fuel supply line, feeding the factory HPFP. The OEM low-pressure fuel pump(s) are redirected to supply the FST, protecting the FST-R pump from fuel starvation. Overflow fuel returns to the OEM fuel filler hose via an included billet adapter. The integrated regulator on the FST-R can be vacuum referenced for 1:1 fuel pressure, or run static to mimic the stock system.
The FST-R mounts in a collision-safe area under the vehicle, in front of the rear bumper support, secured to OEM mounting points via an anodised aluminium bracket. Heat tape is included to reflect exhaust heat. Wiring uses Raychem solderless butt splices with a weatherproof fuse and relay — no soldering required, installs in under 30 minutes.
