Its \u003cstrong\u003eunique port configuration\u003c\/strong\u003e is the point: it plumbs traditional flow-through or dead-head systems, and the \u003cstrong\u003etwo opposing lower return ports flow parallel with the pressure ports\u003c\/strong\u003e, which eliminates the need for elbow fittings and does away with an extra Y-fitting entirely.

It is also the unit Radium designs their vehicle specific mounts around, including the \u003cstrong\u003eCorvette FPR mounts (13-0447, 13-0457, 13-1467)\u003c\/strong\u003e and the \u003cstrong\u003e2015+ Mustang FPR mount (20-1226)\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eOne thing worth knowing before you call anyone: \u003cstrong\u003ea rapid drop in fuel pressure after the pump shuts off is normal\u003c\/strong\u003e for aftermarket regulators of any brand. To regulate high flow, the diaphragm seat and return orifice have to be large, and large sealing surfaces will not form a perfect seal at rest. Pressure resets immediately when the pump runs again. If you also have long cranking or delayed pressure build, that points at the feed hose draining back to the tank, usually a pump module leak or a missing pump check valve, not the regulator.\u003c\/p\u003e\n\u003ch3\u003eKit Includes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMain rotating assembly\u003c\/li\u003e\n\u003cli\u003eMounting bracket with M6x1mm hardware\u003c\/li\u003e\n\u003cli\u003eFour vacuum fittings: 5mm barbed, vacuum plug (returnless), 1\/4in push-to-connect, and 3AN male\u003c\/li\u003e\n\u003cli\u003e6AN ORB plugs (x2) and 8AN ORB plug (x1)\u003c\/li\u003e\n\u003cli\u003e6AN ORB to 6AN male adapters (x3) and 8AN ORB to 8AN male adapter (x1)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eUniversal, any port injection EFI fuel system operating between 20 and 150psi\u003c\/li\u003e\n\u003cli\u003eSingle and multi-pump systems, flow-through or dead-head\u003c\/li\u003e\n\u003cli\u003ePairs with Radium vehicle specific FPR mounts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eImportant Notes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFor port injection EFI systems operating between 20 and 150psi\u003c\/li\u003e\n\u003cli\u003eFuel lines sold separately\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Radium Engineering","offers":[{"title":"Default Title","offer_id":43704168153155,"sku":"20-1100-01","price":199.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0064\/7754\/5539\/files\/6x4_website_20-1100-01.jpg?v=1787405788","url":"https:\/\/www.tunedbyshawn.com\/products\/radium-mpr-multi-port-fuel-pressure-regulator-universal-20-1100-01","provider":"Tuned by Shawn","version":"1.0","type":"link"}
