One honest behavior note applies to every FHST, with the lift pump refilling the canister at its own rate, so sustained demand beyond the lift pump's flow eventually outruns the reservoir; match pump classes to the power target. The 450-class version (20-0701) serves bigger surge pumps.\u003c\/p\u003e\n\u003ch3\u003eKit Includes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1x FHST canister assembly for the 20-0630-00 hanger\u003c\/li\u003e\n\u003cli\u003eWiring components with relay and fuse for one FHST pump\u003c\/li\u003e\n\u003cli\u003ePumps NOT included; second pump wiring via 17-0031\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1995-2001 Nissan 240SX\/Silvia (S14, S15) and 1995-2002 Skyline GT-R (R33, R34) running the Radium 20-0630-00 hanger\u003c\/li\u003e\n\u003cli\u003eGSS342\/AEM 50-1200 pump class; 450-class version: 20-0701\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Radium Engineering","offers":[{"title":"Default Title","offer_id":43672706383939,"sku":"20-0700","price":379.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0064\/7754\/5539\/files\/radium-engineering-rad-20-0700-29454197260358_51bbcb54-3663-4171-ab2e-59bf9927fccd.jpg?v=1786717352","url":"https:\/\/www.tunedbyshawn.com\/products\/radium-fuel-hanger-surge-tank-add-on-for-gss342-or-aem-50-1200-pumps-not-included-1995-2001-nissan-240sx-silvia-and-1995-2002-nissan-skyline-gtr-20-0700","provider":"Tuned by Shawn","version":"1.0","type":"link"}
