Description
The Radium Engineering Fuel Surge Tank (FSTR-RA) Install Kit is the ultimate solution for safely and cleanly installing a surge tank system in your 2013+ Ford Focus ST or 2015+ Focus RS. Designed to protect your engine from fuel starvation during spirited driving, this kit allows the FSTR-RA to feed the high-pressure fuel pump (HPFP) while using the factory low-pressure pump to keep the surge tank filled.
Included is a black anodized aluminum mounting bracket that positions the FST in a collision-safe location beneath the vehicle, just in front of the rear bumper support. The bracket bolts directly to OEM points, making for a secure and clean install. The provided heat-reflective tape helps protect the surge tank system from exhaust heat.
This kit includes everything necessary to complete the install: -6AN Vapor Shield EFI hose, AN and OEM-style fittings, aluminum push-lok hose ends, and a full wiring kit featuring a weatherproof relay and fuse, along with Raychem solderless butt splices for a fast, solder-free installation.
The FSTR-RA features an integrated fuel pressure regulator that can be run static to mimic the stock system or vacuum-referenced for 1:1 fuel pressure adjustment. Fuel overflow returns to the tank via a billet fuel filler hose adapter for seamless reintegration.
Fuel pump required, sold separately. Compatible options include the AEM 50-1000, AEM 50-1200, and Walbro F90000285.
