Shown above is the gauge with the optional in-line Tee fitting. The Radium universal fuel pressure gauge is perfect for this duty. Two additional sizes are included.Ī fuel pressure gauge is needed in order to set and monitor fuel pressure and should be located along on the output line or at the fuel rail. However, should orifice size need to change it can be done easily using common tools. The FST-R comes fully assembled with the correct orifice size for the selected pump. The FST-R is no taller than a standard fuel surge tank with hoses installed. In this case, the vacuum reference hose is not required. Note: returnless fuel systems commonly use a constant fuel pressure. A vacuum line hooks up to the nipple on the FST-R to achieve 1:1 vacuum reference. Pressure adjustment is done using the adjustment screw located on the top cap of the regulator unit. No additional fuel pressure regulator is required. The side port is the regulated pressure output and is plumbed directly to the fuel rail(s). Please see the MORE DETAILS tab on this page (above) for additional info on plumbing a FST-R. If the pump is purchased elsewhere, some assembly will be required. If the pump is purchased as part of the FST-R, the surge tank will come fully assembled and will be pressure tested for leaks and ready to be installed. Note: The FST-R is not available in dual-pump configurations. The FST-R can be configured with all 39mm fuel pumps from many leading manufacturers.

Additional details on the design of the FST-R can be found here. Like all Radium fuel surge tanks, this universal product can be used on any fuel injected application and is compatible with all fuel types. Furthermore, this system permits cooler fuel temperatures as the fuel is not returning from the hot engine bay.

This simplifies the installation, reduces overall cost, reduces weight, and eliminates potential leak points in the fuel system. This revolutionary idea eliminates the need for an external fuel pressure regulator along with the extra fittings and hoses. The high-flow regulator is adjustable and features interchangeable orifice sizes. The FST-R (Fuel Surge Tank–Regulated) is an all new design that houses a single internal fuel pump and has an integrated fuel pressure regulator machined into the top cap. Lifetime warranty on Radium components (excludes fuel pump, hoses and fittings). Fully assembled and leak tested before shipment. Assembled with stainless steel hardware. Nickel-Plated Electrical Connector with 24' Flying Leads. Interchangeable regulator orifice sizes to match output of different pumps. Integrated adjustable fuel pressure regulator with 1:1 vacuum reference. Anodized for compatibility with all fuel types.

Installing a surge tank is also an easy way to upgrade the fuel pump of a vehicle without opening or modifying the OEM fuel tank. Excess fuel in the surge tank is returned back to the vehicle's main fuel tank. In the case of the FST-R (patent pending), the regulator is built in to the surge tank and is re-circulating fuel internally.

This volume is maintained by the main fuel tank's (lift) pump as well as the fuel returning from the fuel pressure regulator. The volume of fuel inside the surge tank acts as a buffer to always keep the FST pump supplied with fuel. The FST fuel pump feeds the fuel rail(s).
