From the FPR, another 8AN PTFE line feeds the front port of a dead head aftermarket fuel rail. The OEM fuel feed line is repurposed as a high flow return connecting directly to the FPR return fitting, and a fuel pressure gauge mounts on the feed line for easy adjustment.\u003c\/p\u003e\n\u003ch3\u003eChoose Your Kit\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eStainless Filter (20-1025-03):\u003c\/strong\u003e 10 micron stainless element, cleanable and reusable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMicroglass Filter (20-1025-05):\u003c\/strong\u003e 6 micron microglass element for the finest filtration\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhat You'll Feel\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAdjustable, gauge-verified fuel pressure on a chassis that offers none from the factory\u003c\/li\u003e\n\u003cli\u003eA full return-style circuit using the OEM feed line rather than fabricating new hard lines\u003c\/li\u003e\n\u003cli\u003eThe regulator an NB hanger install requires, bundled with the filtration and plumbing rather than bought piecemeal\u003c\/li\u003e\n\u003cli\u003eFactory-location filter mounting on a billet mount, no drilling\u003c\/li\u003e\n\u003cli\u003eE85-ready PTFE plumbing from tank to rail\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eRA-series adjustable fuel pressure regulator mounted under the RH strut tower\u003c\/li\u003e\n\u003cli\u003eHigh flow fuel filter with billet OEM-location mount, stainless or microglass element\u003c\/li\u003e\n\u003cli\u003eLarge 8AN feed line around the tank plus 8AN PTFE lines to the FPR and rail\u003c\/li\u003e\n\u003cli\u003eFuel pressure gauge mounted directly on the feed line\u003c\/li\u003e\n\u003cli\u003eAdapter fittings and hardware for a complete installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eThe Details\u003c\/h3\u003e\n\u003cp\u003eThis kit is the fuller of Radium's two answers to the NB regulator problem. On 1999-2005 cars, installing the 20-1020 hanger removes the OEM fuel pressure regulator from the system, and an aftermarket FPR becomes mandatory; the lighter path is the 20-1022 FPR kit, while this kit adds regulation, filtration, and the entire tank-to-rail plumbing run in one box. On 1989-1997 cars the OEM regulator lives on the fuel rail and is unaffected by the hanger, so this kit is an upgrade rather than a requirement, converting the car to a proper high flow return system. It feeds a dead head aftermarket rail at the front port: the Radium 1.6L B6 rail (20-0769-02) or the 1.8L BP rail (20-0369), both carried here and sold separately.\u003c\/p\u003e\n\u003ch3\u003eKit Includes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eRA-series fuel pressure regulator and fuel pressure gauge\u003c\/li\u003e\n\u003cli\u003eHigh flow fuel filter in the selected element with billet OEM-location mount\u003c\/li\u003e\n\u003cli\u003e8AN feed line, 8AN PTFE fuel lines, adapter fittings, and hardware\u003c\/li\u003e\n\u003cli\u003eNOT included: the 20-1020 fuel pump hanger, fuel pumps, and the aftermarket fuel rail\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1989-2005 Mazda MX-5 Miata, NA and NB, with the Radium 20-1020 fuel pump hanger\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eImportant Notes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eRequires a dead head aftermarket fuel rail with a front feed port; the OEM rail is not compatible\u003c\/li\u003e\n\u003cli\u003eOn 1999-2005 cars this kit satisfies the aftermarket FPR the 20-1020 hanger requires; the 20-1022 FPR kit is the alternative if full plumbing is not needed\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Radium Engineering","offers":[{"title":"Stainless Filter (20-1025-03)","offer_id":43700584087619,"sku":"20-1025-03","price":683.95,"currency_code":"USD","in_stock":true},{"title":"Microglass Filter (20-1025-05)","offer_id":43700584120387,"sku":"20-1025-05","price":664.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0064\/7754\/5539\/files\/20-1025.jpg?v=1787343841","url":"https:\/\/www.tunedbyshawn.com\/products\/radium-fuel-hanger-plumbing-kit-1989-2005-mazda-mx-5-miata-20-1025-03-20-1025-05","provider":"Tuned by Shawn","version":"1.0","type":"link"}
