The AirDog II-5G is an all in one premium fuel pump and filtration
system for your 1999-2003 7.3L Powerstroke diesel. This system removes water,
particulates, and entrained air from the diesel fuel. The entrained air
that is separated from the fuel is returned to the tank through a small
return fitting. The fuel is delivered to the engine at the correct
pressure and flow rate to meet the demands of the engine under all
operating conditions.
The AirDogII-5G
DF-165 systems feature a built in adjustible diaphragm pressure
regulator. All AirDog II-5G systems include a complete installation kit.
The AirDog II-5G, for this particular application, is preset at 55-60
psi from the factory for a stock application. The regulator is adjustible up
to 70 PSI so
you can fine tune the system to perfectly match up to your
current and future performance upgrades.
HOW IT WORKS:
The
AirDog II-5G DF- 165 draws fuel from the fuel tank. The fuel is then drawn
through the water separator where 92% of water is removed per SAE spec
1488. It is then pressurized through a Gerotor pump and sent to the 2
micron fuel filter before it is sent to the injection pump. The air from
aerated fuel, due to tank sloshing and engine return lines, is
separated and sent back to the tank through the 3/8” return fitting. The
excess fuel that the engine does not use is recirculated through the
diaphragm regulator back to the suction side of the pump.

Comfortable, warm enough. Feels a bit like a shawl but looks like a good sweater.
I like the color and the fit is good, roomy, feels a bit like a shawl but holds shape and hides a few extra pounds. The zipper is thin but whether you'll find it good enough to last I wouldn't know yet. I'm keeping this.

Comfortable, well put together, nice material, size chart is way off.
Color: Black, Size: 3X-Large
A well put together sweater that is made with very soft yarn, and doesn't seem to have any major structural issues. The zipper works great and the stitching looks like there's not major flaws. The only big issue is the 3XL sweater I got is way off size wise. Oversized sweaters are great, so I was excited about getting this for me to use for day to day wear, and my wife (who is a lot smaller than me) to steal when she's watching tv on the couch or sitting outside, so the disappointment was palatable. Sadly the 3XL size is about the same size as XL sweaters in the closet, where as a few 2xl sweaters we recently ordered from another company are a lot larger than this one.
Outside of the major size discrepancy, which could be a major deal breaker for some, the sweater itself is really comfy and really nice. Sadly 3XL is the largest size we could get on the chart.

Well made for the money.
Beautiful, and well made front zipper sweater. I purchased 7 for Christmas and the men in my family loved the soft feel of the fabric. They were true to size..
