The Titanium Signature Series diesel fuel Systems are the superior fuel System and filtration System, in the diesel industry. This is because here at FASS Diesel Fuel Systems we focus on perfecting our Systems and how they are engineered, taking the extra steps that our competitors ignore while they rush to get product out the door.

By doing this we have less than a 2 percent failure rating with our motor and a design that implements unique design features you can only get with FASS Diesel Fuel Systems.

FASS Whisper Technology (FWT) was engineered to meet the stringent demands of today's quiet diesel engines. FASS Whisper Technology was in development and testing for over two and a half years to meet FASS Fuel System's high quality and durability standards.

FASS Whisper Technology effectively and drastically reduces the sound levels of the Signature Series FASS Diesel Fuel System to a whisper while at the same time increasing fuel flow rates. Our competition reduces noise levels by reducing flow rates.

Performance Radius Cuts (PRC) are an advanced machining technique used to improve the flow of fuel through the FASS System by creating smooth flowing cuts within the aluminum housing. This prevents the reintroduction of air and vapor back into the fuel and to prevent eddy currents from forming within the corner of a 90-degree sharp angle.

FASS Titanium Signature Fuel Systems are the only Fuel Air Separation System that incorporates these exclusive Performance Radius Cuts, lesser competitors commonly use T-Bone and square 90-degree fittings that can limit fuel flow, cause restrictions and reintroduce air back into your fuel.

Mass Flow Return (MFR) technology is used to continually polish your fuel by keeping a positive pressure on the fuel being delivered to the engine to prevent cavitation along with galling and scoring.

Then returning the fuel, that's not yet needed, back to the tank after it has been passed through the filtration process, removing dirt, air, vapor and water. This means your fuel is being constantly Polished (cleaned), guaranteeing that your diesel truck always has the cleanest fuel possible. The MFR in combination with the optional FASS Fuel Heater options will help insure Extreme cold weather operations!

Bolt On Bracket Mounts old mounting styles required drilling or welding when mounting your new System. This has now been simplified with our new bolt on brackets that utilize your Ford Super Duty factory bed bolt, the bolt that secures your truck bed to your frame.

Mounting your Titanium Signature Series System takes only minutes and all brackets are made from machined steel for superior support and strength.

Not full coverage
Size: Medium, Color: A-multicolor(6 Pack)
These are not full coverage and are the cheapest underwear in every way. The fabric is rough, and the seams around the edges of the leg openings are exposed. I ordered medium for my 28" waist and 38" hips. They fit... except for the buttcheek debut. I gave them to my 12 year old daughter to wear because she's not picky. Plus, they were cheap. She's happy. I'm still searching for full coverage undies. Update: The seller reached out regarding my review, and I'm impressed with their customer service. The cotton softened up upon washing and drying (no sand paper undies), and my daughter is very pleased with them.

Comfortable and cool. Does not ride up.
Color: 01-multicolour (4-pack), Size: Medium
Extremely comfortable. Stays cool. Ample coverage. Quality material. They do not creep up. I ordered a medium which I generally take a size small. I have reordered and will reorder again to add more colors to my collection.

Great Value for Cool Thigh Protection
Color: 02-multicolour (4-pack), Size: XX-Large
For the price, I'm not sure there are better women's boxer shortlettes anywhere. I've tried more expensive brands, and for quality and cooling, these are right up there. I have other bamboo viscose undies that still get gross when I get sweaty in the summer, but these, with the large mesh panel, really help wick away a lot of that moisture, keeping you feeling dryer and cooler. I find that the leg openings are comfortable and don't roll up! and the waist band doesn't dig, nor does it roll down. These do not provide any compression, and I wasn't looking for any. I just wanted some cooling, thigh protecting women's boxers that wouldn't break the bank. These are them! Bonus- I've washed them and put them in the dryer (following their instructions), and they haven't shrunk; they look about the same and are nice and soft.

Great for the entire family but expensive
So far so good. The brand of boxers we had been buying changed their style and construction so we needed to find an alternative. These have held up well so far to multiple weeks of frequent washing and wearing from the entire family. We did size up from the usual 6/M we normally buy and ordered large to prevent the legs from rolling up which worked out great. Our daughter likes the length and how soft the fabric is for wearing under skirts and gym shorts and liners stay put without moving or leaking as another reviewer mentioned. Our son says they are comfortable and fit well being just supportive enough without being constrictive. We all agree that there seems to be not enough fabric in the back as they tend to be much tighter across the backside than the front and that also causes the waist band to ride lower in the back than the front. These have better seam placement than some brands we tried with no seam across the lady bits and no seam down the middle of the back side so they are more much comfortable but the cost is also much higher and that is why we're only giving it 4 stars. These will stay in the rotation until we find something cheaper that both us and the kids like.

Pregnant lady review! Soft, comfortable, cool.
Color: 03-multicolour (4-pack), Size: Large
So soft, comfortable and cool. I'm pregnant and I've gained weight in my legs. I love wearing dresses but my thighs were rubbing together too much. These are perfect to wear under dresses. I also wear them under my bibs at work and it keeps me from getting overheated but I don't have to worry about whether or not my underwear show since they just look like shorts. I wish these came in maternity. I just keep them below my belly. I'll be buying more for sure.
