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. If using auxillary port injection, consider this FST kit instead. Here is a informative video on how a Radium Fuel Surge Tank (FST) works:

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(s) are 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 FST 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 FST-R 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.

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

What is Included?
-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

Toeless wonders. Love em!
Color: Classic Color
Not gonna lie. These are a God sent when you have an issue with your toes. I hate my toes feeling constricted so these are phenomenal! Comfortable and well worth the money. I also like my socks thin. If you wear boots or hightops, these might not be what your looking for. I do adore the different shades and you can wear them one way or the other as one side is longer. If worn one way, they are higher up the ankle and vice versa.

no toes covered
Color: Classic Color
i love these socks but there is room for improvement. The top and bottom band make indentions when i wear very long. A smooth stretchy bottom and top would be nice. i wouldn’t recommend for diabetics because of the indentions they make. They are fairly comfortable. But if not pulled on right you will walk on the band and it digs in a little. Also after awhile the top slides down and the foot part slides back. i have to keep readjusting. The material itself is soft. I am wearing and i like them but if i want more i will look for some without the elastic bands top and bottom. I dont like socks because my toes are sensitive and i am more comfortable without my toes covered. These are working for me now. In future will look for something similar.

Toes are grateful
Color: Fresh Color
I generally need more toe room in my shoes, but I don't need wider shoes. These are perfect for that. I took off one star because as I wash them , some of the stitching is coming undone. It doesn't seem to make a huge difference, however, so I still wear them. They are way too comfy to give up !

They fray and unravel after a few washings.
Color: Classic Color
They are exactly what I needed but after a few washings they started to fray and unravel. Also I was looking for black and had to buy the 4 different colors.
