The AirDog II-5G A7SPBF266 DF-100-5G Air/Fuel Separation System from GAP is the latest and greatest in fuel delivery for your 2008-2010 Ford 6.4L Powerstroke (Stock To Moderate).
The AirDog II-5G is the first diesel Fuel Air Separation System to include an integrated diaphragm fuel pressure regulator. This regulator offers better fuel flow at pressure, allows for more fuel pressure adjustability, and can even be boost compensated. In addition, all 5G systems come with upgraded wiring harnesses and connectors.
The AirDog II-5G offers protection and performance like no other lift pump. Their patented air separation, along with a water separator, and fuel filter makes sure the expensive components in your fuel injection system get all the clean fuel they can handle. The AirDog II-5G also overcomes loss of power due to driving in higher altitudes with a factory fuel pump. By eliminating spray pattern disruption due to air entering the system, this system helps to improve overall engine performance. This allows the engine to keep its designed injection timing which allows a more complete burn of the fuel entering the cylinder. This increases engine efficiency across the power and torque range.
The included harness features 12-gauge wiring from the battery all the way to the motor. A Metri-Pack 280 connector replaces the Deutch 2-pin connector which allows more current flow without creating excessive heat. All other connectors in the harness are weather packs to help keep the elements out. This system utilizes the same 4G motor technology that has proven itself to be a reliable, quiet operating system. It also retains the "Demand Flow" from the previous AirDog II variants. Demand Flow means whatever fuel the injection system does not use gets recirculated back through the filter base.

Makes an older family mattress feel brand new
There’s an older mattress in my place that everyone avoids because it feels too worn in the middle. Instead of replacing it, I decided to give this topper a shot. Once it settled on the bed, it added a thick cushioned layer that helped level out the whole surface. Lying down feels smoother, and the middle no longer dips the way it used to. The fabric feels cool when you touch it, and it keeps that same feel even after staying on it for a while. I thought a thick topper might hold warmth, but this one keeps the air moving enough that the bed stays comfortable throughout the night.

Helpful upgrade when staying between short-term housing
Laying it out was quick, and once it settled, the bed instantly felt gentler on the shoulders and hips. The padding feels thick without being bulky, and it molds just enough so that you feel supported without sinking. The airflow is surprisingly good. Even after lying still for long periods, the surface never turns warm or clammy. That was important since the mattress underneath didn’t have much ventilation.

Super comfortable
Color: Green Bamboo(2300gsm), Size: Queen
this mattress topper completely saved my bed. It is super thick and soft, but still gives enough support so you don’t feel totally stuck. The cooling cover actually works pretty well and doesn't trap heat like other memory foam I’ve tried in the past. It was also really easy to put on and the deep pockets keep it from sliding around at night. Very happy with it!
