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.

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.

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.

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

Durable but to hard to chew to make squeak.
Size: 2.5" (Small Dog), Color: Pink+Red+Yellow
Nice and squeaky but a little too hard for my 25# Cockers to chew on...may be the spikes.

Used for tense muscles
Size: 3.5" (Medium/Large Dog), Color: Set of 6
I don’t use these as dog toys. I use them as therapy balls. You place it on an area of tension and lean on it. Works like a charm to take pain away!

An absolute must have in our house
Size: 2.5" (Small Dog), Color: Blue+Orange+Green
We have a couple of miniature Aussies. One is more of a snuggler, but the other is addicted to playing fetch and these balls are her favorite! Perfect amount of bounce and squeak. Perfect size for her mouth and a great value. Very durable too.

loud but in a good way
Size: 4.5"
Love these crazy loud squeeky balls. I bought two a bit too big but the dogs still love them. Yes, they will drive you insane but the dogs love them so much it's worth it watching the pups enjoy the balls. They are strong and safe as long as they aren't too small for your dogs mouth.
