A lift pump, usually the OEM in-tank unit, keeps the tank full, and the volume inside acts as a buffer so the surge pumps never see air even when the lift pump momentarily starves. Because the regulator returns low pressure fuel straight into the surge tank, there is no external FPR return line to plumb and one fewer port fitting than a conventional surge tank. The single feed line dead-ends at the engine.\u003c\/p\u003e\n\u003ch3\u003eChoose Your Version\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWalbro GSS342 \/ AEM 50-1200 \/ DW440 (20-1445)\u003c\/strong\u003e: the common brushed pump package\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBosch BR540 \/ DW400 (20-1446)\u003c\/strong\u003e: larger diameter pumps, maximum of 2 if the fuel level switch is fitted\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWalbro F90000267 \/ 274 \/ 285 (20-1447)\u003c\/strong\u003e: the DCSS 39\/50 package, also accepts F90000295\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhat You'll Feel\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eStable fuel pressure through corners, braking, and low tank levels\u003c\/li\u003e\n\u003cli\u003eA simpler install than a conventional surge tank, with no external regulator or FPR return line\u003c\/li\u003e\n\u003cli\u003eTool-less pressure adjustment by turning a knob, with detents giving roughly 1psi per click\u003c\/li\u003e\n\u003cli\u003eA vacuum reference port that swivels 360 degrees so it can be aimed without tools\u003c\/li\u003e\n\u003cli\u003eCapacity for 1, 2, or 3 pumps as the build grows\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAccepts 1, 2, or 3 fuel pumps; pumps not included\u003c\/li\u003e\n\u003cli\u003eBuilt-in RA-series regulator with tool-less knob adjustment and haptic detents\u003c\/li\u003e\n\u003cli\u003e360 degree swiveling, double O-ring sealed vacuum reference port, 1:1 capable\u003c\/li\u003e\n\u003cli\u003eFour interchangeable 10-32 vacuum port fittings, plus a plug for constant pressure\u003c\/li\u003e\n\u003cli\u003e1\/8in NPT fuel pressure port at the regulator with plug provided\u003c\/li\u003e\n\u003cli\u003ePump outlet: 10AN ORB female, preassembled with an 8AN male adapter\u003c\/li\u003e\n\u003cli\u003eOverflow and supply ports: 8AN ORB female, preinstalled with 6AN male adapters\u003c\/li\u003e\n\u003cli\u003eAnti-rotation high current electrical studs with ring terminals and hardware included\u003c\/li\u003e\n\u003cli\u003eGasoline, ethanol, and methanol compliant internal wiring\u003c\/li\u003e\n\u003cli\u003eIntegrated mounting feet for M6 or 1\/4in fasteners\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eThe Details\u003c\/h3\u003e\n\u003cp\u003ePlan the return before you buy. The overflow port \u003cstrong\u003ecannot be capped\u003c\/strong\u003e, so excess fuel has to go back to the main tank; if your car has no return port on the tank, one must be created, and Radium publishes a technical data sheet covering how. Pump choice carries two real constraints worth knowing up front. Pumps without an integrated check valve, the Bosch BR540 and the Walbro F90000295, should only be used as the primary pump in a staged installation. And the physically larger BR540 and DW400 interfere with the optional fuel level switch, so a tank running that switch is limited to two of those pumps rather than three. The 1\/8in NPT port takes the 0-100psi gauge for setting pressure, and the level switch can drive a dash light, an ECU safety input, or lift pump control.\u003c\/p\u003e\n\u003ch3\u003eKit Includes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMPFST-R surge tank with integrated RA-series regulator\u003c\/li\u003e\n\u003cli\u003eAll parts required to install 1, 2, or 3 pumps\u003c\/li\u003e\n\u003cli\u003ePreinstalled 8AN and 6AN adapter fittings\u003c\/li\u003e\n\u003cli\u003eFour vacuum port fittings and a reference plug\u003c\/li\u003e\n\u003cli\u003e1\/8in NPT plug, ring terminals, and electrical hardware\u003c\/li\u003e\n\u003cli\u003eNOT included: fuel pumps, fuel pressure gauge, and fuel level switch\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eUniversal, any vehicle experiencing fuel starvation from inadequate tank baffling\u003c\/li\u003e\n\u003cli\u003eParticularly suited to forced induction conversions upgrading fueling without opening the stock tank\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eImportant Notes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eThe overflow port cannot be capped; a return to the main fuel tank is required\u003c\/li\u003e\n\u003cli\u003eBosch BR540 and Walbro F90000295 lack check valves and must be the primary pump in a staged setup\u003c\/li\u003e\n\u003cli\u003eOnly 2 Bosch BR540 or DW400 pumps fit when the optional fuel level switch is installed\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Radium Engineering","offers":[{"title":"Walbro GSS342 \/ AEM 50-1200 \/ DW440 (20-1445)","offer_id":43700748746819,"sku":"20-1445","price":645.95,"currency_code":"USD","in_stock":true},{"title":"Bosch BR540 \/ DW400 (20-1446)","offer_id":43700748779587,"sku":"20-1446","price":645.95,"currency_code":"USD","in_stock":true},{"title":"Walbro F90000267 \/ 274 \/ 285 (20-1447)","offer_id":43700748812355,"sku":"20-1447","price":645.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0064\/7754\/5539\/files\/TITLEPICwebsite20-1447.jpg?v=1787352419","url":"https:\/\/www.tunedbyshawn.com\/products\/radium-mpfst-r-multi-pump-fuel-surge-tank-regulated-universal-20-1445-20-1446-20-1447","provider":"Tuned by Shawn","version":"1.0","type":"link"}
