![]() ![]() It should also be mounted away from common collision areas. Choose a bracket below that best fits your mounting needs.įloor and Wall Mount - This bracket is laser cut from aluminum and powder coated black and can be mounted on the side or bottom of the surge tank.įrame Mount - Because this bracket has a 90deg formed bend and is cantilevered, it is constructed from steel for superior strength. Mounting locations near heat sources or moving parts such as suspension components should be avoided. The fuel surge tank can be mounted near the main fuel tank or in the engine bay. Shown above is the gauge with the optional in-line Tee fitting.įor the 20-0368-00 Ti Automotive E5LM FST-R, a 20-0598 check valve is included to prevent backflow, as shown above. The Radium universal fuel pressure gauge is perfect for this duty. Furthermore, this added precision will resist diaphragm flutter and optimize pressure stability.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. Two interchangeable orifices are included with calculated flow diameters to match the fuel pump flow to the regulator. 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. Note: The FST-R is not available in dual-pump configurations. 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. 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. Furthermore, this system permits cooler fuel temperatures as the fuel is not returning from the hot engine bay. Like all Radium fuel surge tanks, this universal product can be used on any fuel injected application and is compatible with all fuel types. 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. 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 Full CNC aluminum construction with O-ring sealed interfaces Need help selecting a fuel pump configuration for your vehicle?

Excess fuel in the surge tank is returned back to the vehicle's main fuel tank. In the case of the FST-R, the regulator is built in to the surge tank and is recirculating 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).
