If you're looking to upgrade your Ford Focus ST or RS, the Radium Engineering FST Install Kit is just what you need! This all-in-one installation kit has everything required to seamlessly install a Radium fuel surge tank (FST-R) in your 2013+ Focus ST or 2015+ Focus RS.
The fuel pump nestled inside the surge tank cleverly replaces and mimics the OEM fuel supply line, ensuring a steady feed to the OEM high-pressure fuel pump (HPFP). It's designed to prevent fuel starvation by redirecting the OEM low-pressure fuel pump(s) to supply fuel directly to the FST. Plus, any overflow fuel conveniently returns back into the OEM fuel filler hose with the help of an included billet adapter.
With the integrated regulator on the FST, you have options! It can be vacuum referenced if you need a 1:1 fuel pressure setup, or you can run it statically to replicate the stock system'whatever fits your needs best.
This MK3 Ford Focus install kit smartly positions the FST-R in a collision-safe area right under the vehicle, just in front of the rear bumper support. The anodized aluminum bracket mounts securely to OEM points, ensuring stability and safety. To keep things cool, heat tape is included to reflect any unwanted heat from the exhaust system.
Wiring is a breeze with this kit! It comes with wiring components that feature flying leads, Raychem solderless butt splices, and a weatherproof fuse and relay to power the FST-R fuel pump. You can assemble everything in under 30 minutes, and no soldering is needed'how easy is that?
Get ready to take your driving experience to the next level with the Radium Engineering FST Install Kit. It's all about making your ride smoother and more reliable!
