The unique integrated 1.85L surge tank completely eliminates fuel starvation. No grinding, bending, or modification of the trunk floor sheet metal is required.\u003c\/p\u003e  \u003cp\u003eThis system is compatible with the following fuel pumps:\u003c\/p\u003e  \u003cul\u003e \t\u003cli\u003eWalbro F90000267\u003c\/li\u003e \t\u003cli\u003eWalbro F90000274\u003c\/li\u003e \t\u003cli\u003eWalbro F90000285\u003c\/li\u003e \t\u003cli\u003eWalbro GSS342 255lph\u003c\/li\u003e \t\u003cli\u003eAEM 50-1220\u003c\/li\u003e \u003c\/ul\u003e  \u003cp\u003eTo simplify aftermarket -AN hose plumbing, the 10AN ORB threaded feed port features a low profile 8AN male fitting and the 8AN ORB threaded return port features a low profile 6AN male fitting. To reconnect the OEM feed and return hoses, barb fittings are also included.\u003c\/p\u003e  \u003cp\u003eThe custom designed stainless electrical studs easily handle the high current demand that compact bulkhead connectors lack. These serviceable connections are properly sealed and impervious to all standard and exotic fuels. Nonconductive acorn nuts are provided to prevent any accidental short circuits. Furthermore, the high quality in-tank wiring is insulated with chemically resistant PTFE. Electrical hardware is included for the fuel pump(s), OEM level sender, and OEM temperature sensor.\u003c\/p\u003e  \u003cp\u003e \u003c\/p\u003e  \u003cp\u003e\u003cstrong\u003eIntegrated Surge Tank\u003c\/strong\u003e\u003c\/p\u003e  \u003cp\u003eA fuel surge tank (FST) is the best solution in preventing fuel starvation. Since 2009, Radium Engineering has been designing numerous FSTs for multiple applications. But after some sanctioning bodies banned externally mounted FSTs, Radium built the first production fuel cell with an integrated surge tank (FCST). Because the FD RX7 can experience high lateral Gs, it inherently suffers from fuel slosh. Fortunately, Mazda manufactured a gas tank with a very large bolt flange pattern (similar to the FCST) permitting various upgrading options.\u003c\/p\u003e  \u003cp\u003eFor a proper FST to function, a lift pump is necessary to maintain volume within the surge tank. This lift pump is located in the rear portion of the OEM sub tank within the Mazda gas tank. Included in the kit is a lift pump mount that snaps onto 3 sides of the OEM sub tank. It also serves as a baffle keeping the lift pump supplied with fuel. Measures were taken to ensure that the lift pump always has fuel to deliver to the surge tank.\u003c\/p\u003e  \u003cp\u003eThe 1\" check ball allows fuel into this tight area during acceleration (above) and traps fuel in during deceleration. The lift pump sends low pressure (high volume) fuel in the FST through a special deflector in the bottom of the surge tank canister. The 24 hole diverter evenly disperses fuel inside the canister preventing air bubbles and foaming. When a low demand for fuel is present, the canister will overflow back into the OEM sub tank.\u003c\/p\u003e  \u003cp\u003eFor the high pressure pumps supplying fuel to the engine, a bespoke stainless steel triple pump mesh strainer is included for proper inlet filtration. Because all compatible fuel pumps utilize integrated check valves, the high pressure pump outlets merge into a single 10AN billet collector.  The returning low pressure fuel from the regulator is sent back into the FST keeping it full. A second 24 hole deflector is used in this location further preventing air bubbles and foaming. All of this happens inside the OEM gas tank.\u003c\/p\u003e  \u003cp\u003e \u003c\/p\u003e  \u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e  \u003cul\u003e \t\u003cli\u003eDrop-In OEM Replacement\u003c\/li\u003e \t\u003cli\u003ePermits 1-3 Surge Pumps plus 1 Lift Pump\u003c\/li\u003e \t\u003cli\u003e8AN Male Pump Outlet Fitting\u003c\/li\u003e \t\u003cli\u003e6AN Male Return Inlet Fitting\u003c\/li\u003e \t\u003cli\u003eFuel Starvation Protection\u003c\/li\u003e \t\u003cli\u003eHigh Current Electrical Hardware\u003c\/li\u003e \t\u003cli\u003eCompatible with Various Pumps\u003c\/li\u003e \t\u003cli\u003eAnodized Aluminum Construction\u003c\/li\u003e \t\u003cli\u003eGasoline and Ethanol Compliant\u003c\/li\u003e \u003c\/ul\u003e  \u003cp\u003e \u003c\/p\u003e  \u003cp\u003e\u003cstrong\u003eIncluded:\u003c\/strong\u003e\u003c\/p\u003e  \u003cul\u003e \t\u003cli\u003eAnodized Aluminum 8AN Male Fitting for Feed\u003c\/li\u003e \t\u003cli\u003eAnodized Aluminum 6AN Male Fitting for Return\u003c\/li\u003e \t\u003cli\u003eAnodized Aluminum 8.5mm Barb Hose Ends for OEM Feed\/Return\u003c\/li\u003e \t\u003cli\u003eAnodized Aluminum Surge Tank Canister\u003c\/li\u003e \t\u003cli\u003eAnodized Aluminum OEM Fuel Sensor Mount\u003c\/li\u003e \t\u003cli\u003eAnodized Aluminum Lift Pump Baffle and Check Ball\u003c\/li\u003e \t\u003cli\u003eFuel Resistant Submersible PTFE Tubing\u003c\/li\u003e \t\u003cli\u003eFuel Resistant PTFE Insulated Wiring\u003c\/li\u003e \t\u003cli\u003eStainless Electrical and Mounting Hardware\u003c\/li\u003e \t\u003cli\u003eStainless Steel Mesh Triple Pump Filter\u003c\/li\u003e \u003c\/ul\u003e  \u003cp\u003e \u003c\/p\u003e  \u003cp\u003e\u003cstrong\u003ePump Configuration Selection\u003c\/strong\u003e\u003c\/p\u003e  \u003cp\u003eIf supplying your own pumps, select the option \"Pumps Not Included\" from the menu.\u003c\/p\u003e  \u003cp\u003eNotes:\u003c\/p\u003e  \u003col\u003e \t\u003cli\u003eWhen purchasing \"No Pumps Included\", the kit will come preassembled as shown.\u003c\/li\u003e \t\u003cli\u003eThere will be enough components included with this option to run all 4 fuel pumps.

A 1\/2\" vapor shield feed hose runs from the fuel pump hanger outlet to a Radium Engineering fuel filter secured to the rear subframe. From there a pre-made -8AN PTFE feed line runs all the way to the engine bay where it is up to the user to adapt the 45 degree hose end to their specific fuel system. The fuel lines clear the OEM fuel pump cover and all suspension related parts. No cutting or drilling is required to get the feed line past the fuel tank.\u003c\/li\u003e \u003c\/ul\u003e  \u003cp\u003e\u003ca href=\"https:\/\/www.prospeedracing.com.au\/Radium-Fuel-Pump-Hanger-Surge-Tank-Mazda-RX7-FD-20-0450-20-0452-20-0453\" style=\"text-decoration:none\"\u003e \u003c\/a\u003e\u003c\/p\u003e","brand":"Radium","offers":[{"title":"Walbro GSS342\/AEM 50-1200","offer_id":48979894534244,"sku":"20-0950","price":1519.0,"currency_code":"AUD","in_stock":true},{"title":"Ti Automotive E5LM Brushless","offer_id":48979894567012,"sku":"20-0951","price":1561.0,"currency_code":"AUD","in_stock":true},{"title":"Walbro F90000267\/274\/285","offer_id":48979894599780,"sku":"20-0952","price":1561.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0745\/6260\/1060\/files\/20-0450.jpg?v=1786558821","url":"https:\/\/kyp.com.au\/products\/radium-fuel-pump-hanger-surge-tank-mazda-rx7-fd-20-0950-20-0951-20-0952","provider":"KYP Performance House","version":"1.0","type":"link"}
