Why GM opted to not include a factory fuel lift pump on all of the early model Duramax's is still a mystery. While the CP3 injection pump is able to draw adequate fuel pressure at stock power levels, anything above that its been proven that fuel pressure quickly begins to drop off, limiting the amount of overall power that can be achieved, as well as decreasing potential fuel economy, and potentially harming the injection pump and injectors due to a lack of lubrication.

The AirDog II-5G is an all in one premium fuel pump and filtration system for your 2001-2010 Duramax 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 8-10 psi from factory for a stock application. The regulator is adjustible up to 55 psi for fine tuning 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 through a 5/8” suction line to reduce the risk of cavitation at the pump. 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.

Be patient with the awful odor and greasy texture because it soaks in and smell dissipates
Size: 60ml
I think i'll edit this review after using consistently for a month or so, but this is my initial impression after 2 uses. First of all, the god awful stench was so off-putting that at first i thought 'there is no way i can use this. It is so disgusting and overbearing'. But it does soak in very quickly and the smell does dissipate if you can just get through it for a bit. (you will not walk around all day smelling awful). So the greasy, oily feeling initially and the awful smell does dissipate and it soaks into the skin beautifully. It is definitely worth continued use to see the results. Just be forewarned if you don't like overbearing bad smells (and i mean it smells like you fell into a pool of insect repellent), you will have to persevere.

ok as part of skin routine, but will take time to see if works
Size: 60ml
I was curious about this product because the idea of a natural product for reducing unwanted hair growth sounded appealing, but my experience was mixed at best. The oil itself feels decent on the skin and didn’t cause irritation for me, which is a plus, especially since it claims to be suitable for all skin types. That said, I did not see dramatic or fast hair-removal results, and it definitely does not work like waxing, shaving, or laser treatments. At most, it seemed like something that might help a little over time with consistent use, but the claims about reducing body hair growth felt stronger than the actual results. If you are buying this expecting a miracle product, you may be disappointed. It may be fine as part of a skincare routine, but I would keep expectations realistic.

Curious to see if it works
Size: 60ml
I’ve started a whole new shaving routine and decided to give this stuff a shot, with what I’ve used thus far I can say the smell is pleasant if you enjoy earthy and floral scents. It has a perfumey scent, but the oil itself left my skin glowing and soft. I’m anxious to continue use!
