{"product_id":"mpfst-multi-pump-fuel-surge-tank","title":"MPFST, Multi-Pump Fuel Surge Tank","description":"\u003ch4\u003eOverview\u003c\/h4\u003e\n\u003cp\u003eA fuel surge tank (FST) is designed to prevent fuel starvation on vehicles with inadequate fuel tank baffling. Fuel is supplied to the surge tank by a lift pump, which in most cases is the OEM in-tank fuel pump. The volume of fuel inside the surge tank acts as a buffer to always keep the FST pump(s) supplied with fuel, even if the lift pump starves momentarily. \u003c\/p\u003e\n\u003cp\u003eThis volume is maintained by the lift pump as well as the fuel returning from the fuel pressure regulator. Excess fuel in the surge tank is returned back to the vehicle's main fuel tank. The surge tank also provides a quick and easy way to upgrade any standard fuel system without opening the stock fuel tank. This is an excellent fueling solution for vehicles installing large demand power upgrades such as forced induction.\u003c\/p\u003e\n\u003cp\u003eRecently redesigned for 2024, the Radium Engineering MPFST is the perfect solution for high power vehicles experiencing fuel starvation during aggressive driving. Multiple high flowing fuel pumps can be used in the surge tank.\u003c\/p\u003e\n\u003cp\u003eThe outlet from the fuel pumps merge into a single outlet simplifying external plumbing. And because the compatible pumps utilize check valves, staging is permitted.\u003c\/p\u003e\n\u003ch4\u003eSpecs:\u003c\/h4\u003e\n\u003cp\u003eThe fuel pump outlet port is 10AN ORB threaded and comes preinstalled with a 8AN male adapter fitting. The overflow, supply and return ports are all 8AN ORB threaded and come preinstalled with 6AN male adapter fittings. All of these fittings can be swapped out with different sizes (sold separately).\u003c\/p\u003e\n\u003cp\u003eIt is very crucial that a surge tank be plumbed exactly as listed below. Installations must not deter from this installation or it will cause function issues and premature parts failures.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eStock tank pump outlet plumbs to the supply port on the MPFST\u003c\/li\u003e\n\u003cli\u003eStock tank return inlet plumbs to the overflow port on the MPFST\u003c\/li\u003e\n\u003cli\u003ePump outlet port on MPFST plumbs to the engine\/fuel rail\u003c\/li\u003e\n\u003cli\u003eReturn port on MPFST plumbs to return port on fuel pressure regulator\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eNote: if you're installing this on a returnless car, you cannot block the overflow port. You must create a return port on your stock tank for the overflow port to plumb to.

Some of the new features and support include:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eUp to 3 Bosch BR540 fuel pumps (DW400)\u003c\/li\u003e\n\u003cli\u003eUp to 2 Ti Automotive E5LM brushless pumps\u003c\/li\u003e\n\u003cli\u003eUp to 3 brushless Bosch pumps (DW440)\u003c\/li\u003e\n\u003cli\u003eAnti-rotation electrical terminals\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eWhen fuel enters the MPFST through the supply and return ports, it gets redirected and runs tangential through the canister creating a swirl pot. This helps eliminate unwanted air bubbles and fuel foam that can affect fuel pump and engine performance.\u003c\/p\u003e\n\u003cp\u003eThe pumps are mounted using an anodized aluminum bracket. All internal wires are gasoline, ethanol, and methanol compliant. The brushless Ti Automotive E5LM MPFST (shown above) utilizes a standard press-in filter sock. All other pumps use the provided stainless steel mesh inlet screen for pre pump filtration shown above. Fuel cannot pass between the 3 independent filtration chambers (A, B, C).\u003cbr\u003e\u003cbr\u003e\u003cem\u003eNOTE: If less than 3 pumps are installed, the empty port does NOT need to blocked off on the inlet screen.\u003c\/em\u003e\u003c\/p\u003e\n\u003cp\u003eThe fuel pump power connections are handled with specially designed anti-rotation high-current electrical studs. Necessary ring terminals and hardware are included with every surge tank.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.radiumauto.com\/cdn\/shop\/files\/FST_Installs_Returnless.pdf\" rel=\"noopener\" target=\"_blank\"\u003ehttps:\/\/www.radiumauto.com\/cdn\/shop\/files\/MPFST12_7a52c784-ef05-42bc-a54d-8c55a7c2f24f.pdf\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.radiumauto.com\/cdn\/shop\/files\/FST_Installs_Returnless.pdf\" rel=\"noopener\" target=\"_blank\"\u003ehttps:\/\/www.radiumauto.com\/cdn\/shop\/files\/19-0402.pdf\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.radiumauto.com\/cdn\/shop\/files\/FST_Installs_Returnless.pdf\" rel=\"noopener\" target=\"_blank\"\u003ehttps:\/\/www.radiumauto.com\/cdn\/shop\/files\/FST_Installs_Returnless.pdf\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eNOTE:\u003c\/p\u003e\n\u003cp\u003eThis item is supplied to order through manufacturer\/suppliers.\u003cbr data-start=\"527\" data-end=\"530\"\u003ePlease allow 2–5 business days for processing before dispatch.\u003c\/p\u003e","brand":"Radium Engineering","offers":[{"title":"20-1440 MPFST Fits Walbro GSS342 or AEM 50-1200 or DW440","offer_id":45282859712691,"sku":"20-1440","price":1087.0,"currency_code":"AUD","in_stock":true},{"title":"20-1441 MPFST Fits Bosch BR540 or DW400","offer_id":45282859745459,"sku":"20-1441","price":1087.0,"currency_code":"AUD","in_stock":true},{"title":"20-1442 MPFST Fits Walbro F90000267\/274\/285","offer_id":45282859778227,"sku":"20-1442","price":1087.0,"currency_code":"AUD","in_stock":true},{"title":"20-0443-00 MPFST Fits Ti Automotive E5LM","offer_id":45282859810995,"sku":"20-1443","price":1087.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0745\/9127\/3139\/files\/20-0443-00_E5LM-b.webp?v=1771442288","url":"https:\/\/velocity-performance-lab.com\/products\/mpfst-multi-pump-fuel-surge-tank","provider":"Velocity Performance Lab","version":"1.0","type":"link"}
