Included in the kit is a lift pump mount that snaps onto 3 sides of the OEM sub tank. This lift pump is located in the rear portion of the OEM sub tank within the Mazda gas tank. Fortunately, Mazda manufactured a gas tank with a very large bolt flange pattern (similar to the FCST) permitting various upgrading options.įor a proper FST to function, a lift pump is necessary to maintain volume within the surge tank. 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. Electrical hardware is included for the fuel pump(s), OEM level sender, and OEM temperature sensor.Ī fuel surge tank (FST) is the best solution in preventing fuel starvation. Since 2009, Radium Engineering has been designing numerous FSTs for multiple applications. Furthermore, the high quality in-tank wiring is insulated with chemically resistant ETFE. 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. The custom designed stainless electrical studs easily handle the high current demand that compact bulkhead connectors lack. To reconnect the OEM feed and return hoses, barb fittings are also included. To 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. This system is compatible with the following fuel pumps: No grinding, bending, or modification of the trunk floor sheet metal is required.
The unique integrated 1.85L surge tank completely eliminates fuel starvation. The Radium Engineering fuel surge tank hanger permits the use of 1, 2, or 3 aftermarket high pressure pumps and 1 lift pump in the stock Mazda FD RX7 fuel tank.

Furthermore, the in-tank wiring is insulated with high quality chemically resistant ETFE. Electrical hardware is included for the fuel pump(s). Non conductive anodized aluminum acorn nuts are provided to prevent any accidental short circuiting. These serviceable connections are hermetically sealed and impervious to all standard and exotic fuels. The custom designed stainless electrical studs easily handle the high current demand that compact multi-pin bulkhead connectors lack. For later model vehicles that use the inverted flare feed line, a replacement PTFE feed hose is provided, as shown in pictures.
If a second pump is installed, an SAE quick connector is provided that snaps into the underside of the fuel hat simplifying installation. Multiple adapter fittings are provided for connecting back to the OEM fuel lines.
