The integrated regulator on the FST can be vacuum referenced if 1:1 fuel pressure is required or run static to mimic the stock system.\u003c\/cite\u003e A complete bolt-in kit containing all necessary parts for installation, plumbing, and powering the surge tank pump.

First, a means for adjusting the FST-R fuel pressure is needed, coming either from special OBDII software such as a COBB Accessport or from Radium's 20-0152 installed on the FST-R outlet port. Second, pump matching matters: depending on the flow rate of the pump installed in the FST, a drop-in fuel pump upgrade may be required in the main tank, since the main tank's pump keeps the surge tank full and wants to flow roughly 40 to 50 percent of what the surge pump flows, an estimate that varies by combination. Select the FST-R and surge pump for the horsepower target, match the lift side accordingly, and the EcoBoost's low pressure side stops being the limit.\u003c\/p\u003e\n\u003ch3\u003eKit Includes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eComplete mounting hardware for the under-vehicle FST-R location\u003c\/li\u003e\n\u003cli\u003eAll plumbing components including the billet OEM filler hose return adapter\u003c\/li\u003e\n\u003cli\u003ePump power wiring components\u003c\/li\u003e\n\u003cli\u003eFuel surge tank and pumps NOT included, sold separately\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e2013-2018 Ford Focus ST (MK3)\u003c\/li\u003e\n\u003cli\u003e2016-2018 Ford Focus RS (MK3)\u003c\/li\u003e\n\u003cli\u003ePairs with Radium FST-R surge tanks; pressure adjustment via OBDII software or Radium 20-0152\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Radium Engineering","offers":[{"title":"Default Title","offer_id":43672699699267,"sku":"20-0365","price":427.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0064\/7754\/5539\/files\/radium-engineering-rad-20-0365-28318281302086_e7cbf8bb-c42b-43d7-9e17-86f7c19d4c31.jpg?v=1786717219","url":"https:\/\/www.tunedbyshawn.com\/products\/radium-fuel-surge-tank-install-kit-2013-2018-ford-focus-st-rs-20-0365","provider":"Tuned by Shawn","version":"1.0","type":"link"}
