Beginning with the 2005 model years, Dodge opted to move the fuel lift pump from being mounted in the engine bay to inside of the fuel tank basket to help avoid the lift pump failures that had plagued them since 1998.5 model years. Overall, it was a positive move on their part as failures were reduced, but it was also quickly determined that especially for those looking to increase the horsepower of their trucks, even a little bit, this pump was completely inadequate. And to make matters worse, this new positioning of the pump inside of the fuel tank made upgrading that much more difficult. Fortunately, AirDog has a complete system that includes all of the components you'll need to make sure you'll never have to worry about fuel pressure again!
The AirDog II-5G is an all in one premium fuel pump and filtration
system for your 2005-2018 Cummins 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 17
psi from the factory for a stock application. The regulator is adjustible up
to 55 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-220 draws fuel 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.

True to size
Size: 9.5, Color: Tusk
I want to start off by saying I ordered a 9 and 1/2 and these fit perfectly so they are true to size. They are fairly comfortable in the heel isn't too high but is wide so they're very stable to walk in. They look great and can be styled in a variety of ways I have worn them with jeans but also a nice sundress and it works both ways. I've been wearing these for several months and they've held up really well and still look great.

Daughter ranks it 5/5. I rank them 4/5 due to heel comfort.
Size: 8, Color: Black, Size: 8, Color: Black
My foot is 9.44 inches long which usually places me in a 7.5. For this chart, it suggested the size 8. It's a perfect fit. The back zipper is easy enough to use. You don't even really need to undo the top strap once you have it adjusted to your preferred spot. My foot is narrow to normal around the heel and I'm wider in the toe box. These heels accommodate that well. I have plenty of room around my toes. The toe strap isn't smashing down either. The shoes seems well-made. The straps do not have a threads hanging. There's no sloppy glue drips around the bed. The bottom is strong and the heel is solid. I'm not a huge fan of thicker/chunky heel looks usually. I like the skinner heel styles mostly but ... there's a big positive to the chunky heels. They're very easy to walk in. Great heels for non-formal occasions. The bottom is not slippery. The cushioning around the toes in very nice. My only complaint is that the cushioning by the heel feels inadequate- especially at this price. It feels like you're walking on a block of wood. For that reason, I gave them to my middle schooler. She's thrilled. She pranced around the house in them testing them out for herself. She adjusted well to walking in them and she finds them comfy.

Lucky Brand womens Herrika
Size: 9, Color: Smoke Grey
These shoes are some of the comfiest heels I've ever worn! The heel actually has a nice height to it, but it's at a gentle slope that feels very comfortable. The heel itself is thicker, which makes it easier to walk, and I love the ankle strap for added security. The shoe's construction is solid, the materials are durable, and the zipper at the back of the ankle moves smoothly. I got the smoke grey color, which I think is really more of a lighter skin tone color, so I don't really agree with the name, but the color is accurately represented by the photos on the product page. This is a great neutral shoe that will pair with many different outfits. It's high quality and versatile, so I think it's well worth the cost. I love my new shoes!

Well made, true to size, comfortable, and attractive looking!
Size: 12, Color: Black
Wife was wanting a new pair of heels for a work party she has coming up and I happened to see these and thought they strongly resembled what she was looking for so I got them as a surprise for her. They arrived a few days ago and she tried them on that night and wore them around the house and to work a couple times to see how she likes them. So far, she is extremely pleased with them! She said they fit perfect and she's had no issues with comfort wearing them all day for work. She really likes the wider heel as it gives her more stability. Her favorite thing so far though has been all the compliments/comments she's getting from the other ladies in her office about them.

Lucky Brand nailed it with these sandals. The craftsmanship of the leather is top notch. I love the look of the crossover straps, they add a chic touch to any outfit. The fit is fantastic, I ordered my usual size 9 and found them to be perfectly true to size.
