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

I stay on your foot they don’t slip in your shoe

This is the only socks I wear Under Armour because they stay in place I wear a size 8, but they’re more comfortable with a large instead of a medium, but I wear both because I have them already and you can pull them to stretch them out a little bit

Great fit, truly doesn’t slide off heel

I’ve scoured all the lands looking for a no-show sock that was 1) thin, 2) quality, soft, breathable material, 3) didn’t dig into my feet/heels, 4) doesn’t shrink, and most importantly 5) stays on the back of my heel without a bulky non-slip rubber piece and these check all the boxes! Perfect for low profile women’s work shoes like Keds, etc. Not low enough for most flats though. I wear a women’s size 9.

So good - I’m buying MORE.
Number of Items: 3, Color: White (3-pairs), Size: Medium
I’m gonna give you more detail than you need about why I’m buying these socks again. I’ve been the mom of girl athletes. I’ve been a model and a fashion director. I’ve worn every brand of shoe on the planet and never found a shoe that did NOT find a vulnerable spot on my foot to rub raw. Even my beloved white Jack Purcell sneakers. With that said - I don’t like socks. I’ve bought a TON of them in 35+ years.....all major brands. They shift. They lose their shape. They get holes in them and wear out too fast. Not these. I retired this year, and knowing I’d be in sneakers a lot, traveling, sightseeing ...... I bought these 6 months ago and have worn them constantly. I’ve traveled with them. I’ve washed them in hot water and bleach. The socks are like brand new. They are exactly the right cut so as not to be seen in a basic sneaker. The little silicone patch on the heel stays put. Not once have I had to dig down into my shoe and pull the sock back up. The socks have stayed soft and EXACTLY the same as the day they were new. Like I said - I am back to buy them again. Great quality!
