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.

True to size & color, modest cut, fitted style
Color: Purple, Size: Small
The cut on these tops are perfect. It's a nice v-neck without being revealing. Thick straps and solid back so your bra doesn't show. Sizing is accurate in my case. 5'6" 130lbs chest 34" waist 26" hips 39" and I ordered the small which is fitted on me. I ordered the lavender purple and a black one and both colors are correct in shade. Soft and stretchy material. I air dry them mostly and only gentle low on the dryer if needed and have not had any shrinking.

Great top for summer!
Color: Navy Blue, Size: Large
I bought one of these. The v-neck and fit of the tank top is amazing! Flattering! I loved it so much I ordered two more. Great summer tank! Washes and dries fabulously as well. I am 5’4” 150lbs, wear a medium or size 8-10. I purchased a large and love the look. It fits well, not too tight but hugs the body. Not oversized.

Comfortable Fit without over compression
Size: 38B, Color: Gentle Rose
This is a good post surgical bra. I had a lumpectomy and it gave me enough support without being too tight. It is adjustable in the front and the shoulders. Use the size chart to get your best fit. Soft material. Comfortable enough I wore it 24/7 for a couple days. Only downside is handwashing but I will try the delicate cycle on my machine and air dry always.

Awesome bra!
This bra is so comfortable. I love the fact that you can adjust the straps and the front to make it fit a short person's torso. This bra lifts and so far, has not stretched out.

Soft and Comfortable
Size: 46D, Color: Black
Size 46 D, black. Very Comfortable ! The strap adjustments are in front so it would be easy for someone who needed a caregiver to help them dress. The cups fit well with no gaps or wrinkles and the back lays smoothly, with no irritating seems or crossovers. The chest band is one piece, so no irritating seams, and its a little more supportive than my usual at home or bedtime bras. I tried it on and decided to wear it an hour to see if it stayed comfy while I moved around the house. It was so comfortable I forgot to change it! I ordered the black and when I machine washed it there was no dye bleeding. Hung to dry. Wearing it again and I think it just might become my new favorite. If I still love it, I might purchase another color in next month's shopping budget.
