RADIUM DOES NOT OFFER A WARRANTY ON ANY FUEL PUMPS! FUEL PUMPS CAN BE RETURNED IN UNUSED CONDITION WITHIN 30 DAYS OF PURCHASE. SEE TERMS AND CONDITIONS FOR MORE INFORMATION.

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

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

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.

RADIUM FST-R
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. The high-flow regulator is adjustable and features interchangeable orifice sizes. This revolutionary idea eliminates the need for an external fuel pressure regulator along with the extra fittings and hoses. This simplifies the installation, reduces overall cost, reduces weight, and eliminates potential leak points in the fuel system. 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. Additional details on the design of the FST-R can be found here.

The FST-R can be configured with all 39mm fuel pumps from many leading manufacturers. 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. If the pump is purchased elsewhere, some assembly will be required.

Please see the MORE DETAILS tab on this page (above) for additional info on plumbing a FST-R.

The side port is the regulated pressure output and is plumbed directly to the fuel rail(s). No additional fuel pressure regulator is required. Pressure adjustment is done using the adjustment screw located on the top cap of the regulator unit. A vacuum line hooks up to the nipple on the FST-R to achieve 1:1 vacuum reference. Note: returnless fuel systems commonly use a constant fuel pressure. In this case, the vacuum reference hose is not required.

The FST-R is no taller than a standard fuel surge tank with hoses installed.

Two interchangeable orifices are included with calculated flow diameters to match the fuel pump flow to the regulator. Furthermore, this added precision will resist diaphragm flutter and optimize pressure stability.


A 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. The Radium universal fuel pressure gauge is perfect for this duty. Shown above is the gauge with the optional in-line Tee fitting.

For the 20-0368-00 Ti Automotive E5LM FST-R, a 20-0598 check valve is included to prevent backflow, as shown above.

More than a daily grind
Color: Purple
We are very happy so far, working very well. The grind is even and easy to adjust with a simple turn of the screw on the base of the grinder. The automatic light is a nice feature, especially as I am 66 and my eyes are not what they used to be. Once I turned the on button to face front, I'm no longer triggering a grind just by picking these up. (our last grinders trigger was on the top of the unit}. They feel well constructed and are easy to fill. My wife absolutely loves the color (purple). will update this in a couple months for durability, but for the price so far (1 month) 5 stars

Electric grinders
Color: Black/Black
Easy to refill. We use pink Himalayan salt and the grinder does well. It seems to struggle a bit with the peppercorns bit still gets the job done. The light is nice. We have enjoyed the ease of use. It also looks nice on the counter. The holder is great as it catches any fine debris after use. I purchased this one as it uses actual batteries and not something else I have to charge. They have been used daily for 2 months and have not needed to change the batteries yet.

I Feel Like a Fancy Chef Every Time I Season My Fries
Color: Green
This Salt and Pepper Grinder, Electric Automatic has officially upgraded my kitchen from “microwave expert” to “TV cooking show contestant.” One button press and suddenly I’m seasoning food with dramatic confidence like I know exactly what I’m doing. The automatic grinding works smoothly and quickly, and I love how consistent the grind size is. Whether I want a fine sprinkle or a coarser grind, it handles both perfectly. The motor is surprisingly strong, and it doesn’t struggle or jam like some cheaper grinders I’ve used before. The design also looks sleek and modern sitting on the counter. It feels comfortable in the hand, easy to refill, and the clear container makes it simple to see when it’s time for more salt or pepper. Huge bonus: no wrist workout required. My manual grinder used to make me feel like I was training for an arm wrestling tournament. I’ve been using it daily, and now even scrambled eggs get five star restaurant treatment. Friends noticed it immediately and asked where I got it which made me feel unnecessarily sophisticated for someone eating frozen pizza. Overall, convenient, stylish, and genuinely useful. If you want effortless seasoning with a little extra kitchen drama, this grinder is a winner
