Why GM opted to not include a factory fuel lift pump on all of the
early model Duramax's is still a mystery. This lack of consistent fuel pressure coupled with the switch from the proven CP3 to a CP4 injection pump beginning in model year 2011 has spelled disaster on these trucks, especially for those trying to increase the horsepower through performance programmers and/or larger displacement injectors. Even at stock power levels, this insufficient fuel pressure and volume equates to limited overall power, decreased 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 2011-2016 LML 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-220 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-220 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.

LADIES this makes my long Hair feel much thicker and healthier. So NOT just for the Dudes.
Size: 16 Fl Oz (Pack of 1)
First off I am a woman and my Nephews were here for Christmas and tossed a bottle of the Bourbon Oak in the trash on the way out to head home. Well I wondered what it was and there was enough in it to try it for 2 weeks...LOL. So I did. OMG my Hair is thanking my Nephews for that. So I used that up and bought this one.
LOOK LADIES...yeah it isn't a Lady Scent but what it did for my long hair means I will keep buying this. I was using Viori for over a year and that is great stuff, cut down on my tangles in a big way. This CREMO made my Hair feel and really seem Thicker. as well as I have less fallout of hair. I would have to clean my brush daily. I have not pulled the hair from my brush since the day before Christmas. I still am in shock about that part. My Fine hair is long to the middle of my back, and gray or salt n pepper. I am not young anymore by a long shot, and Cremo has given my hair something it needed for years. I also find I do not have to wash my hair as often as I did before. I can go 4 days, when before it was 3 maximum. My hair has more moisture, is so much healthier, no greasiness at all. I wash once and leave it on for the time it takes to wash up the rest of me and rinse well. Follow up with Viori Conditioner just for the detangling. I think I don't really need the Viori as the backup but still use it.
OK the Scent is fine and not too strong, but it does last til I wash my hair again. Cremo don't change a thing.
I am thrilled with this brand of Shampoo/Conditioner. Oh Yeah.

Highly Recommend, Smells Amazing, Enjoyed by the both of us.
Size: 16 Fl Oz (Pack of 1)
I'm a woman and I'm obsessed with alll of the Cremo Italian Bergamot products that have come out recently! I got this for me, my husband and son. I just got the new hand soap! I'm getting ready to get the body spray for my 5th grader, who's getting into cologne and I have a perfume obsession so I'm having fun. My husband has this Cremo Italian Bergamot Body Wash too, and since I never know what he wants and put other products in, and this Cremo Italian Bergamot 2-1 Shampoo and conditioner is his main go to, because it runs out the most. I love it on my hair too! I really enjoy Bergamot as the opening scent in my favorite perfumes.
