Improve the fuel system on your 2008-2010 Ford 6.4L Powerstroke (Stock To Moderate) with the AirDog A4SPBF070 FP-100-4G Air/Fuel Separation System from GAP.
Your diesel engine needs better fuel flow when you upgrade its parts and performance. Vacuum at the fuel pump and agitation in the fuel tank are both increased by higher fuel flows. This causes more air/vapor to enter the fuel system and lowers the engine's performance. Injector barrel/plunger assembly galling, pitting, and tip erosion can also be brought on by air and vapor. The AirDog eliminates air from the fuel that might harm your injectors permanently and keep your engine from operating as it should. Additionally, the AirDog offers the fuel pressures and flows your diesel engine needs to operate at peak efficiency.
This AirDog system incorporates the 4G motor they have been using for years with excellent success together with their conventional nonadjustable/high flow return base. By keeping this fundamental layout, AirDog is able to provide a reasonably priced system with a well-proven and dependable motor design.
The AirDog operates by pulling fuel from the fuel tank containing entrained air/vapor, particulate contaminates and unknown quantities of moisture. Fuel passes through the water separator that removes water and large particulate contaminates. Next, the fuel with only entrained air/vapor and tiny particulate contaminates remaining, enters the fuel pump. Under positive pressure flow, the fuel passes through the fuel filter and the remaining particulate contaminates are caught and contained, the entrained air/vapor is also separated and returned to the tank. The clean fuel then flows at the proper pressures up to your engine. Each kit includes plumbing, hardware, wiring harness, mounting bracket, and all components needed for installation.
AirDog has engineered this system to remove water, particulates, vapor, and entrained air from diesel fuel. This lift pump and filter system is what your vehicle needs to deliver clean fuel to your engine.

Excellent shirt that compares to box brand stores and fits very well.
Size: 15"-15.5" Neck 34"-35" Sleeve, Color: Light Blue
I recently lost 44 pounds and all of my dress shirts no longer fit correctly. These are an excellent replacement. I am 6'2" and now 180 lbs. These are a perfect fit and are slim where they need to be and don't bunch up on the sides, and they are super comfy.
Bottom of the shirt is long enough to keep tucked in even when bending over. Sleeve length is decent, they do slide up past my wrists when doing extreme reaches, but are right at the hand/wrist connector when in an idle pose.
They did have a weird chemical smell when I first put them on, but let them air out when you first put them on. They are also very wrinkled, so make sure you have an iron around. No status on durability, but the material is not super thin, its thick like Target shirts.

Good fit, good quality, great price
Size: 16"-16.5" Neck 32"-33" Sleeve, Color: Carbon
I ordered a few of these in different patterns. They fit great (I used to be a L/XL, now I'm down to a M/L). The price is a third of similar shirts from other Men's stores and fit the same. They look great with jeans or slacks, tucked or untucked, with or without a jacket.

Nice, but...
Size: 16"-16.5" Neck 32"-33" Sleeve, Color: Tulip
The shirt is nice and fits well. However, it's not slim fit. It's just regular fit and "slim fit" should be removed from the description.

Stylish shirt
Size: 14"-14.5" Neck 32"-33" Sleeve, Color: Ash Green
Perfect fit and size, as promoted. The quality and feel (comfort) are nice. The color is a little lighter than what I could see on the screen, but I liked it. The shirt is not too thin or thick.
